RATS AND MICEGuid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx). 
People envision many different things when thinking about rats and
mice. Some consider them as vermin or pests, many envision laboratory
specimens, others think of them as snake food, while a chosen
population treasure them as pets. These rodents make excellent pets for
children if they are cared for properly. They seldom bite when raised
as pets and are handled with care.
These timid and social pets are fun to watch performing their natural
behaviors of burrowing, searching for food, and playing. Unlike their
wild counterparts that are typically nocturnal, pet rats and mice have
periods of activity both day and night. Rats and mice are inexpensive,
easy to care for, and responsive to handling.
Handling
Pet rodents become tame and seldom bite when properly restrained and
accustomed to handling. Some rats can be very territorial of their
cage, and these should be coaxed out of the cage before being handled.
Mice housed individually may be more aggressive and apprehensive than
those housed in groups. Most mice and rats enjoy being handled away
from their cage. Rats and mice can easily picked up by scooping them
into a can or cupped hands. For any rodent, never pull on the tip of
the tail because the skin can easily tear and become stripped from the
tail.
Housing
Several types of cages are available that are suitable for housing
small rodents. Many of these units come equipped with cage
e¨furniturei´ such as exercise wheels, tunnels and nest boxes as added
luxuries. Such accessories, as well as sufficient litter depth within
which to burrow, are desirable for the peti´s psychological well-being.
Cages should be constructed with rounded corners to prevent chewing.
Rodents will readily chew through wood, light plastic and soft metal;
so recommended caging materials are wire, stainless steel, durable
plastic and glass. Beware that glass and plastic containers drastically
reduce ventilation and can lead to problems with humidity, temperature
and odor concentration. Make sure that the enclosure is escape proof
because these little rodents are known escape artists.
Rodents do very well in solid bottom cages with deep bedding and ample
nesting material. Shredded paper and processed corncob are preferred
bedding. Cedar chips or chlorophyll scented shavings should be avoided
because of association with respiratory and liver disease. At lease one
inch of bedding should be provided to allow for normal burrowing
behavior. Cotton and shredded tissue paper make excellent nesting
materials. Adult mice require a minimum floor area of 15 square inches
and a cage height of 5 inches. Rats need at least 40 square inches of
floor space and a minimum of 7 inches in height. The cage and
accessories should be cleaned thoroughly once to twice weekly. Cages
are sanitized with hot water and nontoxic disinfectant or detergent,
and then thoroughly rinsed. Water bottles and food dishes should be
cleaned and disinfected daily.
Pet rats and mice can be housed singly or in groups. These rodents are
colony oriented by nature. However, occasionally an overly aggressive
mouse or rat may have to be caged individually. Territorial disputes
also develop when the cages are overcrowded or when they lack food or
water. Group cages should be provided with multiple food and water
sources.
Water
Always provide fresh water for your pet. Fresh water should be provided
daily, not only when the bottle empties. Water is easily provided in
water bottles equipped with sipper tubes. This method also helps keep
the water free from contamination. Always make sure that the tubes are
positioned low enough to allow the pet easy access.
Food
In the wild, these animals feed on leaves, seeds, roots, fruits and
insects. Current recommendations for feeding in captivity are pelleted
rodent ration containing 14% protein and 4% fat. Seed diets are also
formulated for mice and rats, but these diets should only supplement
the basic rodent pellet as a treat item. Rodents prefer sunflower-based
diets to pellets, but these seeds are low in calcium and high in fat
and cholesterol. When fed exclusively, seed diets can lead to obesity
and nutritional deficiencies.
