Ball Pythons

 Natural History

Ball pythons (Python regius) are found at the edges of the forest land of Central and Western Africa. They are equally comfortable on the ground and in trees. They are crepuscular, active around dawn and dusk. Called royal pythons in Europe, here in the United States we call them "balls" due to their habit of curling themselves up into a tight ball when they are nervous, their heads pulled firmly into the center. Like most pythons, ball pythons are curious and gentle snakes.

Ball pythons typically reach 4 feet (1.2 m) in length; occasionally there are specimens that reach 5 feet (1.5 m). When properly fed, their bodies become nicely rounded. Like all pythons and boas, ball pythons have anal spurs. These single claws appearing on either side of the vent are the vestigial remains of the hind legs snakes lost during their evolution from lizard to snake millions of years ago. Males have longer spurs than do the females; males also have smaller heads than the females.

Ball pythons, like all pythons and boas, devour a variety of prey in the wild - amphibians, lizards, other snakes, birds and small mammals. They do not eat mice in the wild, however, and do not recognize the mice we offer them as being something edible. Thus, imported wild-caught ball pythons tend to be very picky eaters, at least initially, and drive their owners to distraction in their attempts to get them to eat something.

Ball pythons are reputed to be able to go for extended periods of time without food; wild-caught ball pythons have gone for a year or more without food until finally enticed to eat lizards and other snakes. This is not a healthy trait and must not be a reason for selecting this species. This should also make you suspicious when a pet store tells you that their ball pythons are eating well.

Buying captive-born ball pythons reduces the stress on the threatened populations in the wild and helps ensure you will get a healthy, established eater and a snake already used to contact with humans. Buying from a reputable breeder will ensure that you will get the help and advice you need to assure that your ball feels comfortable and secure enough to eat after you bring it home and let it get settled for a week or so.

With the increased popularity of reptiles as pets there is increased pressure on wild populations. In addition to the more than 60,000 ball pythons that are imported annually, ball pythons are killed for food and their skin is used for leather in their native land. For some reason, despite their low reproduction rate, wild ball pythons are the least expensive pythons on the market, generally wholesaling for under ten dollars. Imported ball pythons also harbor several different types of parasites that may go unnoticed by the novice snake owner. All around, it is better to buy a captive-born hatchling or an established, well-feeding juvenile, sub-adult or adult than an imported ball of any age.

In captivity, young ball pythons will grow about a foot a year during the first 3 years. They will reach sexual maturity in 3 to 5 years. The longest living ball python on record was over 48 years old when it died. Egg-layers, female ball pythons encircle their four to ten eggs, remaining with then from the time they are laid until they hatch. During this 3-month period, they will not leave the eggs and will not eat.

Getting Started

Selecting Your Ball Python
Choose an animal that has clear firm skin, rounded body shape, clean vent, clear eyes, and who actively flicks its tongue around when handled. All ball pythons are naturally shy about having their heads touched or handled by strangers; a normal reaction is for the ball to pull its head and neck sharply away from such contact. When held, the snake should grip you gently but firmly when moving around. It should be alert to its surroundings. All young snakes are food for other, larger snakes, birds, lizards and mammalian predators so your hatchling may be a bit nervous at first but should settle down quickly.

Selecting an escape-proof enclosure
Select an enclosure especially designed for housing snakes, such as the glass tanks with the combination fixed screen/hinged glass top. All snakes are escape artists; ball pythons are especially powerful and cunning when it comes to breaking out. A good starter tank for a hatchling is a 10-gallon tank (approximately 20"L x 10"W [50 x 25 cm]). A young adult requires a 20-gallon tank, and full adult may require a 30 gallon tank (36" x 12"W [91 x 35 cm]).

Select a suitable substrate
Use paper towels at first. These are easily and quickly removed and replaced when soiled and, with an import, will allow you to better monitor for the presence of mites and the condition of the feces. Once the animal is established, you can use more decorative ground cover such as commercially prepared shredded cypress or fir bark. Pine and aspen shavings should not be used as they can become lodged in the mouth while eating, causing respiratory and other problems. The shavings must be monitored closely and all soiled and wet shavings pulled out immediately to prevent bacteria and fungus growths. The utilitarian approach is to use inexpensive Astroturf. Extra pieces can be kept in reserve and used when the soiled piece is removed for cleaning and drying (soak in one gallon of water to which you have added two tablespoon of household bleach; rinse thoroughly, and dry completely before reuse). Remember: the easier it is to clean, the faster you'll do it!

Provide a hiding place
A half-log is available at pet stores. An empty cardboard box or upside-down opaque plastic container, both with an access doorway cut into one end, can also be used. The plastic is easily cleaned when necessary; the box can be tossed out when soiled and replaced with a new one. The box or log must be big enough for the snake to hide its entire body inside; you will need to eventually replace it as your snake grows. Ball pythons prefer dark places for sleeping and, as they are nocturnal, they like the dark place during our daylight hours; they also like to sleep in something that is close around them, so do not buy or make too big of a cave for its size. Place a nice climbing branch or two in the tank with some fake greenery to screen part of it; your ball will enjoy hanging out in the "tree."

Keeping it warm
Proper temperature range is essential to keeping your snake healthy. The ambient air temperature throughout the enclosure must be maintained between 80°F to 85°F (27-29° C) during the day, with a basking area kept at 90°F (32.5°C). At night, the ambient air temperature on the coolest side may be allowed to drop down no lower than 73° to 75°F (23-24°C) only if a basking area of at least 80°F (27°C) remains available.

Special reptile heating pads that are manufactured to maintain a temperature about 20 degrees higher than the air temperature may be used inside the enclosure. There are adhesive pads that can be stuck to the underside of a glass enclosure. Heating pads made for people, available at all drug stores, are also available; these have built-in hi-med-lo switches and can be used under a glass enclosure. You can also use incandescent light bulbs in porcelain and metal reflector hoods to provide the additional heat required for the basking area. All lights must be screened off to prevent the snake from burning itself.

All pythons, especially ball pythons, are very susceptible to thermal burns. For this reason do not use a hot rock. New on the market are ceramic heating elements. They radiate heat downwards, do not emit light, and are reported to be long lasting. Plugged into a thermostat they will enable you to adjust the temperature inside the tank as the ambient room temperature changes with the seasons.

Buy at least two thermometers - one to use in the overall area 1 inch (2.5 cm) above the enclosure floor, and the other 1 inch (2.5 cm) above the floor in the basking area. Don't try to guess the temperature - you will either end up with a snake who will be too cold to eat and digest its food or one ill or dead from overheating.

Humidity
Ball pythons are native to generally temperate to arid areas. Depending on where you live, they may be fine with the ambient humidity. If there are any problems shedding, or feces are dry when deposited or there is straining to defecate, check the humidity with a hygrometer and get it up to 50 percent. When shedding, they will need higher humidity: increase enclosure humidity to 60 to 65 percent, or mist daily during the shed. If you bathe them in a warm bath the day their eyes clear, they should shed completely within 24 hours.

Lighting
No special lighting is needed. Ball pythons are nocturnal snakes, spending their days in the wild securely hidden away from possible predators. To make it easier to see your ball during the day, you can use a full-spectrum light or low wattage incandescent bulb in the enclosure during the day. Make sure the snake cannot get into direct contact with the light bulbs as ball pythons are very prone to getting seriously burned. Respect your ball's needs, however, and be sure to provide a hide box, and expect them to use it!

Feeding

Allow your snake to acclimate to its new home for a couple of weeks. Start your hatchling (about 15" in length) off with a single pre-killed 1-week to 10-day old "fuzzy" mouse. A smaller sized hatchling may require a smaller mouse; try a pre-killed 5-day old. Older ball pythons may be fed larger pre-killed mice or pinkie rats. If you have not had any experience force feeding a snake, you may not want to try it yourself until you have seen someone do it. Force feeding, whether of a mouse or with a formula inserted by catheter and syringe, is very stressful for the snake (and it isn't much fun for the owner!). If your new ball has gone several months without eating and is beginning to noticeably lose weight, take it to a reptile veterinarian or contact your local herpetology society and ask to speak to someone who is knowledgeable about ball pythons and feeding problems. A good inexpensive book that covers some of the tricks to enticing reluctant ball pythons to feed is The Care and Maintenance of Ball Pythons by Philippe de Vosjoli, or the new edition, The Ball Python Manual, by de Vosjoli, Dave and Tracy Barker and Roger Klingenberg.

Water
Provide a bowl of fresh water at all times. Your snake will both drink and soak, and may defecate, in it. Check it daily and change when soiled. Soaking is especially good just before a shed. When they eyes clear from their milky opaque, or "blue" state, soak the snake in a tub of warm water for ten minutes or so, then lightly dry it off, and return it immediately to its tank; it should shed cleanly within twenty-four hours.

Health Problems

Routine veterinary care for newly acquired snakes is essential. Many of the parasites infesting ball pythons and other reptiles can be transmitted to humans and other reptiles. Left untreated, such infestations can ultimately kill your snake. When your snake first defecates, collect the feces in a clean plastic bag, seal it, label it with the date, your name and phone number and the snake's name, then take it and your snake to a veterinarian who is experienced with reptiles. There it will be tested and the proper medication given if worms or protozoan infestations are found.

Common problems encountered in captivity include retained eye shed (spectacles) and mites. When snakes shed their skin, the layer of skin over their eye is also shed, and can be clearly seen when looking at a piece of head shed. Always check your ball's head shed to assure it has shed the spectacles. If one or both spectacles have been retained, bathe the snake again in warmish water for about ten minutes. Before returning it to the enclosure, place a dab of mineral oil on that eye with a cotton-tipped swab. The spectacle should come off within twenty-four hours. If it does not come off, wrap your four fingers with transparent tape, sticky side out. Gently rock your fingers from left to right (or, from nose to neck) across the eye; the spectacle should come off. If this does not removed the spectacle, then seek veterinary assistance.

Mites are a sign of poor environmental conditions. Adult mites are tiny reddish brown dots barely bigger than the period at the end of this sentence. You may first notice them swarming over your hand and arm after you have handled your snake (don't worry--they are harmless to humans) or see them moving around your snake's body or clustered around the eyes. Mites are harmful to snakes, especially ones that have not been kept properly. On the positive side, they are easy and relatively inexpensive to get rid of, although the process is time-consuming. Snakes, including ball pythons, should routinely shed is one piece, from snout (including spectacles) to tail-tip. If a snake does not shed cleanly, it is a sign that something is not right, either with the snake or with its environment. Newly acquired snakes may not shed properly for the first month or two as they are getting acclimated to their new surroundings. This is a sign of transient stress. If it continues, or begins to occur in a long established snake, the snake must be evaluated for possible health problems, and the snake's environment must be evaluated for humidity problems.

Humidity and Ball Pythons

Ball pythons are native to very warm, but not hot, dry areas in Africa. Many people make the mistake of trying to keep them in a too humid overall environment, using damp sphagnum moss or misting them frequently throughout the day. The problem with this is that keeping the overall environment damp leads to conditions such as blister disease where in the skin, usually of the belly, becomes covered with blisters, leading to bacterial infections of the skin, which in turn leads to overall health problems.

In fact, all a ball python needs is an area within its dry enclosure to which to retreat when it requires higher humidity. One way to accomplish this is to provide a water bowl large enough for the snake to soak in when it wants. Depending on the ambient room (and thus enclosure) humidity, this may be enough, or may be enough during part of the year.

Handling your New Snake

After giving your ball a couple of days to settle in, begin picking it up and handling it gently. It may move away from you, and may threaten you by lashing it's tail and hissing; don't be put off - it is usually just a bluff, and snakes, like most reptiles, are very good at bluffing! Be gentle but persistent. Daily contact with each other will begin to establish a level of trust and confidence between you and your snake. When it is comfortable with you, you can begin taking it around the house. Don't get overconfident! Given a chance and close proximity to seat cushions, your ball will make a run (well, a slither) for it, easing down between the cushions and from there, to points possibly unknown. Always be gentle, and try to avoid sudden movements. If the snake wraps around your arm or neck, you can unwind it by gently grasping it's tail and gently unwrapping it from around your neck or arm - do not try to unwrap it by moving the head. Some snakes are a bit sensitive about being handled soon after they have eaten. If you feed your snake out of its enclosure, go ahead and replace it back into it's enclosure after it has finished eating. Then leave it be for a couple of days. As the snake gets more comfortable with you, it will be less nervous and less likely to give you back your mouse.

Necessities

Some things you should have on hand for general maintenance and first aid include: Nolvasan (chlorhexidine diacetate) for cleaning enclosures and disinfecting food and water bowls, litter boxes, tubs, sinks, your hands, etc. Betadine (povidone/iodine) for cleansing scratches and wounds. Set aside a food storage bowl, feeding and water bowls, soaking bowl or tub, even sponges, to be used only for your snake.

Enjoy Yourselves

You have a companion that will be a part of your life for a great many years if taken care of properly. They should remain alert and active well into their old age. The main causes of death of snakes in captivity are directly related to their care: improper temperatures, contact with heating and lighting elements, no regular access to water, lack of necessary veterinary care and treatment, careless handling--all things for which we, as their caretakers, are directly responsible.

Boa Constrictor (Red Tailed Boa)

Take a moment and ask yourself a couple of very important questions such as: do you really want a snake that will get to be 10 feet long, weigh over 50 pounds, urinate and defecate like a St. Bernard, should live more than 30 years and for whom you will have to kill mice, rats and, eventually, small rabbits? Many people think that it will be easy to find someone who will take it if they decide they don't want their boa when it is 8 or 10 feet long. So, take a look at the classified ads--they always have sale ads for big pythons and boas. The zoo doesn't want any more--they already have more giant snakes than they need. The local herpetology societies and reptile veterinarians always have big snakes for which they are trying to find homes. At 8 feet and 40 pounds, a 2-year old boa may already be eating rabbits a couple of times a month and can be very unwieldy to handle alone. You have to interact with them constantly to keep them tame--do you want a hungry, cranky 10-foot snake mistaking your face for prey? Another consideration is who is going to help you clean its enclosure? Take it to the veterinarian when it's sick? Take care of it when you go away to school or on vacation? No matter how much they love you, there are some things a mother, and your friends, will not do! Owning a big snake is not cool; it is a major, long-term commitment and responsibility.

There has been a disturbing increase since 1996 of boas being dumped by their owners on animal shelters and reptile rescues, many of whom tried to sell the 6+ foot boa only to find that, no matter how much they reduced their price, no one was interested in buying. Many of these snakes are in terrible condition, with respiratory infections, riddled with endo- and ectoparasites, many suffering severe injury and infection from untreated rat bites and thermal burns. This is a clear indication that many people who are buying boas shouldn't be.

Natural History

The name "Red-Tail Boa" has commonly been used by pet stores and snake aficionados to detract the public's attention from the fact that their proper name is boa constrictor. Many people who do not know much about snakes are fearful of all "constrictors," especially large constrictors; Red-Tail Boa sounds much less threatening. In fact, not all boa constrictors are red-tailed. While many boas on the market are true red-tailed Boa constrictor constrictor imported from Brazil, with a few coming from very limited areas in Columbia, the Amazon, Guyana, and Surinam, most are actually B. c. imperator from Columbia, with a few coming in from Mexico, Hogg Island and countries throughout Central America. There are seven other subspecies of B. constrictor from South America, which can sometimes be found in the retail and private pet trade. All of the Boa ssp. are listed as threatened on Appendix II of the Convention on the International Trade in Endangered Species; the Argentine Boa (B. c. occidentalis) is on Appendix I--the endangered listing. Appendix II animals can be exported and imported with the proper permits, and can legally be sold through the pet trade; Appendix I animals require special permits to buy, sell, trade and own.

Ranging from the high cloud forests to the dry low lands, these beautifully marked snakes are only moderately arboreal. Frequently found near human habitation (due to the quantity of rodents found near human habitats), boas are primarily nocturnal or crepuscular (active at dawn and dusk). In the extreme northern and southern portions of their range, the boas will often go through several weeks of inactivity to get through the periods of extreme cold or drought, a behavior that may be observed in captivity as the weather changes throughout the year. Those snakes living in the consistently high humid temperatures of the rain forest areas will remain active throughout the year.

Boas devour a variety of prey in the wild - amphibians, lizards, other snakes, birds and mammals. In captivity, they should be fed pre-killed mice, rats and, when adults, rabbits and chickens. You can buy the rodents and rabbits at pet stores; these animals have been specially raised and are clean, healthy and well nourished. Chickens can be purchased at hatcheries; do not feed raw chicken pieces purchased at the grocery store - up to 80% of it may be infected with Salmonella bacteria. Chickens from hatcheries should also be considered suspect due to the overcrowded conditions typical of most hatcheries; check the hatchery out first before you buy. Under no circumstances should you feed your snakes wild-caught prey items. Wild rodents and other animals carry a variety of parasites and bacteria for which your snake has no immunity. If you cannot afford to buy the proper food, you should not buy the snake.

That cute little 2-ounce, 14" to 22" hatchling laying cupped in the palm of your hand will increase its size by up to 300% in its first year, reaching 5 to 6 feet during that time. The following year will add another 3 to 4 feet to its length, as well as several pounds. After the second year, the growth rate slows down significantly, but snakes do continue to grow, however slightly, during their entire lives. The live bearing females will give birth to 10 to 60 young (depending upon the subspecies) after a gestational period of 4 to 10 months (depending upon temperature and several other factors). Unlike most big snakes, many female boas do not bear young each year.

Selecting Your Boa Constrictor

Choose an animal that has clear firm skin, rounded body shape, clean vent, clear eyes, and who actively flicks its tongue around when handled. When held, the snake should grip you gently but firmly when moving around. It should be alert to its surroundings. All young snakes are food for other, larger snakes, birds, lizards and mammalian predators so your hatchling may be a bit nervous at first but should settle down quickly. Like the pythons, boas have anal spurs. These single claws appearing on either side of the vent are the vestigial remains of the hind legs snakes lost during their evolution from lizard to snake millions of years ago. Males have longer spurs than do the females. There is little difference in temperament between the two sexes. Imported Colombian B. c. imperator and B. c. constrictor are the nicest, least aggressive of all the boas. The other true red-tails tend to be testy and aggressive. Captive-bred boas of all subspecies tend to be more docile than their wild-caught counterparts.

Housing

Snake-Proof Enclosure

Select an enclosure especially designed for housing snakes, such as those with the combination fixed screen/hinged glass top. All snakes are escape artists; Boas are especially powerful and can easily break out of a tank sealed with a board and a couple of bricks. A good starter tank for a hatchling is a 20-gallon tank. After the first couple of years, you will have to build your own enclosure out of wood and glass or Plexiglas or purchase a tank made by producers of large reptile enclosures. Be prepared - big snakes need lots of room, not the least of which is an enclosure big enough for you to get in and clean it out!

Suitable substrate
Use paper towels at first. These are easily and quickly removed and replaced when soiled and, with an import, will allow you to better monitor for the presence of mites and the condition of the feces. Once the animal is established, you can use more decorative ground cover such as commercially prepared shredded cypress or fir bark. Pine, cedar and aspen shavings should not be used as they can become lodged in the mouth while eating, causing respiratory and other problems. The bark must be monitored closely and all soiled and wet portions pulled out immediately to prevent bacteria and fungus growths. The utilitarian approach is to use inexpensive Astroturf. Extra pieces of Astroturf can be kept in reserve and used when the soiled piece is removed for cleaning and drying (soak in a solution of two tablespoons of household bleach in for each gallon of water; rinse thoroughly, and dry completely before reuse). Remember: the easier it is to clean, the faster you'll do it!

Hiding Place
A hiding place should be provided for boas. A half-log (available at pet stores), an empty cardboard box or upside-down opaque plastic container, both with an access doorway cut into one end, can also be used. The plastic is easily cleaned when necessary; the box can be tossed out when soiled and replaced with a new one. Many boas enjoy hanging out on branches; provide clean branches big enough to support the boa's weight. If you use a found branch, soak first in the bleach/water solution, then clean water to thoroughly rinse; place in cage only when completely dry. If you use rocks and bricks to construct a cave, be sure to affix them firmly in place. Boas are very strong, and can easily topple such a structure when moving about. When the rocks tumble on the snake, severe injuries may result.

Temperature Gradient
The proper temperature range is essential in keeping your snake healthy. The ambient daytime air temperature throughout the enclosure must be maintained between 82°-90°F (28°C-32°C), with a basking area kept at 90°F-95°F (32°C-35°C). At night, the ambient air temperature may be allowed to drop down no lower than 78°F to 85°F (26°C-30°C). Special reptile heating pads that are manufactured to maintain a temperature about 20 degrees higher than the air temperature may be used inside the enclosure. There are adhesive pads that can be stuck to the underside of a glass enclosure. Heating pads made for people, available at all drug stores, are also available; these have built-in high-medium-low switches and can be used under a glass enclosure. You can also use incandescent light bulbs in porcelain and metal reflector hoods to provide the additional heat required for the basking area, or the new ceramic heating elements which can be put into regular light sockets and radiate heat downward. All lights must be screened off to prevent the snake from burning itself. All snakes are susceptible to thermal burns. For this same reason do not use a hot rock. Buy at least two thermometers - one to use in the overall area 1" above the enclosure floor, and the other 1" above the floor in the basking area. Ideally, you should place a third thermometer at near the upper basking bench or branch. Don't try to guess the temperature--you will end up with a snake who will be too cold to eat and digest its food. Once your snake has grown quite large, you may wish to invest in a pig blanket, a large rigid pad for which you can buy a thermostat to better control the temperature.

No special lighting is needed.

You may use a full-spectrum light or low wattage incandescent bulb in the enclosure during the day but snake, having evolved to living underground, have not need for regular full-spectrum/UV lighting. If you do use such a light in the tank, make sure the snake cannot get into direct contact with the light bulbs, nor burrow itself into the casing of the fluorescent hood.

Feeding

Allow your snake to acclimate for a couple of weeks to its new home. Start your hatchling off with a single pre-killed week- to 10-day old "fuzzy" rat. A smaller sized hatchling may require a small mouse. Larger boas may be fed larger pre-killed rats. The rule of thumb is that you can feed prey items that are no wider than the widest part of the snake's body. While boas will often gladly eat prey that is actually too large for it, they will generally regurgitate the prey item one or more days later. Not a pretty sight. If you have not had any experience force feeding a snake, you may not want to try it yourself until you have seen someone do it. Force-feeding should be an action of last resort, as it is very stressful for the snake--and the owner! It is very easy to overfeed captive snakes, especially the boas and pythons, as they do not get enough opportunity to exercise and burn calories in captivity as they do in the wild. Be judicious--your snake will get big and impressive soon enough. Feed it enough to keep it healthy, not obese.

Provide Fresh Water

Keep a bowl of fresh water available at all times. Your snake will both drink and soak, and may defecate, in it. Check it often and change it as needed. A warm bath in your bathtub will also be welcomed just before your boa is ready to shed.

Veterinary Care

Routine veterinary screening for newly acquired snakes is essential. Many of the parasites infesting boas and other reptiles can be transmitted to humans and other reptiles. Left untreated, such infestations can ultimately kill your snake. When your snake first defecates, collect the feces in a clean plastic bag, seal it, label it with the date, your name and phone number and the snake's name, and take it and your snake to a vet who is experienced with reptiles. Ask that it be tested for worms and protozoans, which are two different tests. If either test is positive, your boa will be given medication given that you can repeat later at home.

Handling Your New Snake

After giving your boa a couple of days to settle in, begin picking it up and handling it gently. It may move from you, and may threaten you by doing tail lashings and hissing. Be gentle but persistent. Daily contact will begin to establish a level of trust and confidence between you and your snake. When it is comfortable with you, you can begin taking it around the house. Don't get over-confident! Given a chance and close proximity to seat cushions, your boa will make a run (well, a slither) for it, easing down between the cushions and from there, to points possibly unknown. Always be gentle, and try to avoid sudden movements. If the snake wraps around your arm or neck, you can unwind it by gently grasping it by the tail and unwrapping it from around you. If you start at the head, you will find that your snake is stronger than you are, or at least, more tenacious.

Necessities

Some things you should have on hand for general maintenance and first aid include: Nolvasan (Chlorhexidine diacetate) for cleaning enclosures and disinfecting food and water bowls, litter boxes, tubs and sinks etc. Betadine (povidone/iodine) for cleansing scratches and wounds. Set aside a food storage bowl, feeding and water bowls, soaking bowl or tub, even sponges, to be used only for your boa.

Places to Go, Things to See and Learn

Join your local herpetological society where you can meet other reptile owners, learn more about your boa and find an experienced reptile veterinarian in your area. Check for a list of herp societies and reptile vets in your area. You might also want to join one of the snake-related email discussion lists and talk with other boa and python keepers.

Burmese Pythons

THINK!!!

Do you really want a snake that may grow more than 20 feet long or weigh 200 pounds, urinate and defecate like a horse, will live more than 25 years and for whom you will have to kill mice, rats and, eventually, rabbits? Many people think that when they decide they don't want their Burmese any more--when it gets to be 8 or 10 or 15 feet long--it will be easy to find someone who does. Take a look at the animal classifieds - they always have sale ads for big pythons. The zoo doesn't want any more. The local herpetology societies and reptile veterinarians always have big pythons for whom they are trying to find homes. Burmese are increasingly being abandoned at vets and animal shelters and are being euthanized for lack of proper homes for them. Breeders keep breeding them, however, because so many people are willing to buy these 'cool' giants, knowing full well they'll be dumped when they're 'too' big.

At 10 feet and 40+ pounds, a 3-year old Burmese is already eating rabbits a couple of times a month and is very difficult to handle alone. You have to interact with them constantly to keep them tame - do you want a hungry, cranky 100-pound, 12-foot snake mistaking your face for prey? Who is going to help you clean its enclosure? Take it to the vet when it's sick? Take care of it when you go away to school or on vacation? No matter how much they love you, there are some things a mother or friends will not do!

Owning a giant snake is not cool - it is a major, long-term, frequently very expensive responsibility. Not only that, but even the nicest, gentlest of Burmese can become killers, even when not very large.

Natural History

The Burmese python (Python molurus bivittatus) is native throughout Southeast Asia. While Burmese are being captive bred in the U.S. and Europe, native populations are threatened. All giant pythons have historically been slaughtered to supply the fashion industry with exotic skins. The exportation of young snakes for the pet trade and for their blood and gall as used in folk medicine has put additional pressures on the wild populations. If you must buy a Burmese, buy a captive-born animal.

These diurnal rain forest dwellers range from areas of lush vegetation lining the river banks up to the montane forests. Equally at home on the ground and in trees, they are also excellent swimmers, and always enjoy a nice, long soak in warm water, especially just before they are ready to shed.

Burmese breed in the early spring. Females lay their eggs in March or April; their clutches range from 12-36 eggs. Females encircle their eggs, remaining with then from the time they are laid until they hatch; during this time, they will not leave the eggs and will not eat. Once the hatchlings cut their way out of their eggs, they are on their own.

They devour a variety of prey in the wild - amphibians, lizards, other snakes, birds, and mammals. In captivity, they should be fed pre-killed mice, rats, and rabbits. You can buy the prey at pet stores and from private breeders and suppliers; these animals are clean and healthy, and you can always find a source that uses humane methods of euthanasia. If you live in a more rural area, you may be able to find free-range chickens; store- and hatchery-bought chicks should be avoided due to the problem with Salmonella. Under no circumstances should you feed your snakes wild-caught prey items. Wild rodents and other animals carry a variety of parasites and bacteria for which your snakes have no immunity. If you cannot afford to buy the proper food, you should not buy the snake.

Selecting Your Burmese Python

Choose an animal that has clear firm skin, a rounded body shape, clean vent, clear eyes and that actively flicks its tongue around when handled. When held, the snake should grip you gently but firmly when moving around. It should be alert to its surroundings. All young snakes are food for other, larger snakes, birds, lizards and mammalian predators so your hatchling may be a bit nervous at first but should settle down quickly. Like all pythons and boas, Burmese have anal spurs. These single claws appearing on either side of the vent are the vestigial remains of the hind legs snakes lost during their evolution from lizard to snake millions of years ago. Males have longer spurs than do the females, and have tails that are wider at the base (tail-end of the vent); otherwise, there is little difference in temperament between the two sexes.

 

Getting Started

Build or purchase a strong snake-proof enclosure. Select an enclosure especially designed for housing snakes, such as the Critter Cottages (TM) with the combination fixed screen/hinged glass top. All snakes are escape artists; Burmese are especially powerful when it comes to breaking out. A good starter tank for a hatchling is a 55-gallon tank. After the first couple of years (and some bigger commercially available enclosures), you will have to build your own enclosure out of wood and glass or Plexiglas. Some people partition off a large part of a room or convert a walk-in closet into a suitable Burmese "tank." Be prepared - giant snakes need lots of room, not the least of which is room enough for you to get in there and clean it out! Remember that your snake will grow rapidly, even when fed conservatively, so you must always buy or build an enclosure much bigger than the present size of your Burmese.

Suitable Substrate

Use paper towels, butcher paper or unprinted newsprint at first. These are easily and quickly removed and replaced when soiled and will allow you to better monitor for the presence of mites and the condition of the feces. Once the animal is established, you can use decorative ground cover such as commercially prepared shredded cypress or fir bark; do not use orchid bark. Pine, cedar and redwood shavings should not be used as they can become lodged in the mouth while eating, and due to the oils (most especially in any cedar product), may cause respiratory infections and other problems. The shavings must be monitored closely and all soiled and wet shavings pulled out immediately to prevent bacteria and fungus growths. The utilitarian approach is to use inexpensive Astroturf( TM) and linoleum. Extra pieces of Astroturf can be kept in reserve and used when the soiled piece is removed for cleaning and drying (soak in one part bleach to 30 parts water; rinse thoroughly, and dry completely before reuse). Remember: the easier it is to clean, the faster you'll do it! Linoleum is easy to clean and disinfect and, when used on the floor and a couple of inches up the walls of wooden enclosures, will help preserve the wood from the acidic urates.

Hiding Place

A hiding place should be provided for Burmese pythons. A half-log (available at pet stores), an empty cardboard box or upside-down opaque plastic container, the latter two with an access doorway cut into one end, can also be used. The plastic is easily cleaned when necessary; the box can be tossed out when soiled and replaced with a new one. Once your snake outgrows these easily replaced hide boxes, you will need to use your imagination. Eventually, you can use a large kitty-litter pan or suitably modified garbage can. Once the snake reaches ten feet, you will have to put your imagination (or hammer and nails and wood) to work to devise increasingly larger enclosures.

Temperature Gradient

Proper temperature range is essential to keeping your snake healthy. The ambient air temperature throughout the enclosure must be maintained between 85F-88F during the day, with a basking area kept at 90F. At night, the ambient air temperature may be allowed to drop down no lower than 78F to 80F. Special reptile heating pads that are manufactured to maintain a temperature about 20F higher than the air temperature may be used inside the enclosure. There are adhesive pads that can be stuck to the underside of a glass enclosure (unfortunately, when the time comes to move your snake to a larger tank, the heating pad cannot easily be removed from the old tank and reused). Heating pads made for people, found at all drug stores and supermarkets, are also available; these have built-in high-medium-low switches and can be used under or inside a glass or wood enclosure. You can also use incandescent light bulbs in porcelain and metal reflector hoods to provide the additional heat required for the basking area. All lights must be screened off to prevent the snake from burning itself, and bright lights must be turned off at least 12 to 14 hours a day to mimic a proper photoperiod; if kept under lights all the time, the snakes will stress and may become ill. If the proper temperatures cannot be maintained without the incandescent light, then you must use another source of non-light emitting or dim light emitting heat. All pythons are very susceptible to thermal burns and for this reason a hot rock must not be used. Buy at least two thermometers: one to use 1 inch above the enclosure floor in the cooler side, and the other 1 inch above the floor in the basking area. Don't try to guess the temperature. You will end up with a snake who will be too cold to eat and digest its food. Once your snake is bigger, invest in a pig blanket, a large rigid pad for which you can buy a thermostat to better control the temperature.

Special Lighting

No special lighting is needed. You may use any incandescent bulb in the enclosure during the day, and a suitable red, blue or nocturnal reptile light at night. Snakes do not require ultraviolet B wavelengths. Make sure the snake cannot get into direct contact with the light bulbs. If they climb into the fluorescent tube fixture, they may pop out and break the bulb--an expensive and potentially lethal accident.

Feeding

Allow your snake to acclimate for a week or two to its new home. Start your hatchling (about 22" in length) off with a single pre-killed week to 10-day old "fuzzy" rat. A smaller sized hatchling may require a small mouse. Older Burmese may be fed larger pre-killed rats. The rule of thumb is that you can feed prey items that are no wider than the widest part of the snake's body. While Burmese (most of whom are bottomless pits when it comes to putting down food) will often gladly eat prey that is too large for their size, they will generally regurgitate the prey item one or more days later--not a pretty sight. If you have not had any experience force feeding a snake, you may not want to try it yourself until you have seen someone do it. It is very easy to overfeed Burmese as most of them are always eager for food, whether they need it or not. Be judicious--you will end up with a giant snake soon enough. Just feed enough to keep it healthy, not obese.

Water

Provide a bowl of fresh water at all times; your snake will both drink, soak and may defecate in it. Check it and replace with fresh water as necessary. Bowls should be big enough for the snake to get into and soak before its sheds. As the snake gets too big for suitably sized tubs in its enclosure, it will have to be taken out and bathed in a secured and safe bathroom.

Veterinary Care

Routine veterinary screening for newly acquired snakes is essential. Many of the parasites infesting Burmese and other reptiles can be transmitted to humans and other reptiles. Left untreated, such infestations can ultimately kill your snake. When your snake first defecates, collect the feces in a clean plastic bag, seal it, label it with the date, your name and phone number and the snake's name, and take it and your snake to a vet who is experienced with reptiles. There it will be tested for parasites (which the majority of pet trade reptiles have) and the proper medication given.

Handling your New Snake

After giving your Burmese a couple of days to settle in, begin picking it up and handling it gently. It may try to move away from you and may threaten you by twitching its tail and hissing. Be gentle but persistent. Daily contact will begin to establish a level of trust and confidence between you and your snake. When it is comfortable with you, you can begin taking it around the house. Don't get over-confident! Given a chance and close proximity to seat cushions, your Burm will make a run (well, a slither) for it, easing down between the cushions and from there, to points possibly unknown. Always be gentle and try to avoid sudden movements. If the snake wraps around your arm or neck, you can unwind it by gently unwrapping it starting at the tail end, not the head.

Necessities

Some things you should have on hand for general maintenance and first aid include: Nolvasan(R) (chlorhexidine diacetate) for cleaning enclosures and disinfecting food and water bowls, litter boxes, tubs and sinks etc. Betadine(R) (povidone/iodine) for cleansing scratches and wounds. Set aside feeding and water bowls, and a soaking bowl or tub for the sole use of your snake.

Bad Press - And Often Deservedly So

Giant pythons have been in the press quite a bit, all due to the fact that their owners died as a result of improper handling of their snakes. While admittedly the press sensationalizes in order to better sell papers, the fact of the matter is that not only is there still a great deal of morbid fear on the part of the general public as regards snakes in general, and giant pythons in particular, but there is also a great deal of stupidity being displayed by many giant python owners (such as by those owners who are surprised to find that their ten foot snake left their backyard to go exploring the neighborhood when left outside for a bit of sun).

And for every story that the press "neglects" to correct, such as the man who actually suffered a fatal heart attack while watching TV with his python, rather than being killed by it, the press also fails to point out what was being done improperly by the snake owner at the time of the "attack." If you smell like food to a snake, especially some of the giant pythons who seemingly contain a bottomless pit instead of a finite stomach, you will be grabbed. And since most people's reaction when being grabbed by a mouth full of fangs in a head the size of a cantaloupe is to flinch and draw away, the snake, sensing live "prey," does what a snake ought to do--bite harder to retain a good grip on the "prey" (hopefully your arm and NOT your face) and coil and constrict around it to begin the process of suffocation. In the case of the unfortunate Canadian snake owner who was killed, his python was not very big, but a) the owner was highly intoxicated at the time, b) the snake was in shed and its eyes were fully opaque and c) the snake was known to be temperamental in general. So not only was the snake feeling particularly cranky and intolerable of human interaction, its human was too intoxicated to act, and react, appropriately.

According to one hospital emergency room physician who has made a study of snake bites, he found that the majority of bites happen to young adult males (late teens through mid-twenties) who are intoxicated at the time of the "attack." On the flip side, though, is the unfortunate Colorado family whose young teenage son was napping when he was attacked and killed by the family's eight foot pet Burmese, a snake who had been free-roaming in the house ever since it was brought home as a hatchling.

While it is true that you are more likely to die in an automobile accident, it is also true that in the past year alone, the number of deaths attributed to and actually caused by pet pythons has more than tripled. As a direct result of the irresponsible actions of these python owners, cities and states are enacting ordinances and legislation banning or severely restricting the private ownership of large pythons - in many cases any snake of any species that reaches 6 or more feet in length.

Before You Buy

Go to a zoo that has an adult specimen. Check out your local herpetological societies to find other giant python owners and ask if you can be allowed to visit their snake, and, if possible, handle it. Few pet stores actually have full-grown adult specimens.

Check out your city, county and state laws to see if there are any restrictions on owning a giant python or boa. Cities who have experienced terror because someone let their Burmese get out of the house have been passing increasingly stringent regulations prohibiting, or severely governing, the ownership or possession of large snakes.

If you have small children, or children will have access to the room in which the snake will be kept, ask yourself whether you can properly secure the snake so that, not only is there no chance for it to escape, but there is no way for young fingers to undo the cage.

Remember that regardless of how tame your Burmese becomes, and no matter how long you have had it, it is still a wild animal and as such is to be considered unpredictable and potentially dangerous. (A tame 8', 56 lb one, free roaming since the family bought it as a hatchling, killed the family's 14 year old, 5 ft. tall, 99 lb son who was apparently napping at the time of the attack...the autopsy evidence showed that the boy tried to get the snake's mouth and body off of him - his hands were perforated with teeth marks, his torso bearing bruise marks from the constriction...[Colorado, 1994]. In this particular case, there was no apparent reason for the attack.
