HOUSING YOUR PET RODENT
What type of cage does my pet rodent require?
It is most convenient to house pet rodents pets in a glass aquarium, although
cages are available specifically for these pets. Wooden cages are not suitable
as rodents love to chew and can really destroy their homes. The cages can be
left open at the top providing that the pet can't escape and other pets (such
as the family dog or cat) can't get to the pocket pet. ALL PET RODENTS ARE
MASTERS OF ESCAPE. The cages must be escape-proof. Letting a pet rodent
have free run of the house is DISCOURAGED, due to the potential for injury and
death to the pet, as well as to destruction of furniture by the pet. They can
be handled outside of the cage if care is used (supervise young children). The
environmental temperature should be kept between 65° and 85°F (18-29°C); warmer
temperatures predispose pet rodents, especially guinea pigs, to heat stroke.
My pet seems lonely. Can I house more than one rodent in each cage?
While it is most common to have a single or occasionally a pair of animals,
several generalities can be made regarding group housing:
1. If a male and female are housed together, especially if they were paired
at any early age, mating will occur.
2. Never house opposite species in the same cage (i.e. a rat and a mouse).
3. If a pet rodent has been housed alone, it is best not to introduce a new
friend to it as fighting is likely to occur.
Guinea pigs can be housed together. Sometimes they fight when they are put
together but you should let them sort out their pecking order. This may take
a couple of days. Sometimes guinea pigs will continue to squeak at one another
intermittently and appear to be aggressive. Do not worry they are just reestablishing
the pecking order.
Hamsters are best housed individually. Sexually mature females are aggressive
to other females and to males. The exception is with animals which have been
housed together from an early age. Housing litter mates together can of course
result in unintentional incest!
Male mice are usually housed alone. Female mice rarely fight and are often
housed together. Newly assembled male groups, new males entering established
territories, and mice previously housed alone are more likely to fight.
Unlike mice, rats rarely fight and can be housed in groups. Occasionally,
females that have just given birth may fight with other females.
Gerbils are usually housed individually. A monogamous pair can be formed if
the male and female are bonded before 8 weeks of age. The pair should not, as
a rule, be separated.
Does my pet rodent need bedding in his cage?
Wood shavings, such as pine or cedar, are usually provided for bedding material.
Shredded paper or towels are also fine. Avoid sawdust, sand, or dirt. The cage
should be cleaned and the bedding changed as often as it gets dirty, but at
least weekly. A major cause of respiratory disease in a pet rodents is poor
environmental ventilation, which allows ammonia from the urine to build up and
irritate the pet's airways. A frequently cleaned, well-ventilated environment
is important in controlling respiratory infections. Any toys should be cleaned
weekly as well.
Can I give our pet any toys?
Regarding cage toys, these can provide psychological stimulation as well as
exercise for the pet rodents. Tubes and mazes are popular, as are exercise wheels.
"Open track" exercise wheels, can be dangerous. Pet rodents, especially hamsters,
can easily become injured by getting a foot trapped in the wheel. Most of the
hamsters have severe injuries; leg amputation is required to treat the problem
(humane euthanasia is also an option). While not every animal with an exercise
wheel will be injured, it is a risk best avoided. The safest wheel is composed
of plastic and has no openings in the track ("solid track") where a foot can
What else do I need in the cage?
Since rodents like to burrow, it is recommended to provide some type of hiding
place for them in the cage. Round, hollow objects can be purchased at the pet
stores, or cleaned cans (such as an orange juice can) or paper towel cardboard
rolls can be provided. If using a can, be sure there are no exposed metal pieces
that can cause injury; with paper towel or toilet paper rolls, expect the pet
will probably chew these up rather quickly, so they will need to be replaced
Anything else I need to know?
Pet rodents are very sensitive to heat stroke. It is critical to keep their
environmental temperature at or below 85°F (29°C), and make sure their "house"
is well ventilated.
