Hamster cages are very important when owning a hamster, because
this is where they will spend their time. There is no such thing as a cage too
big for a hamster, but you do have to be careful about bar spacing. Hamster
cage bar spacing should be no more than a 1/2 inch. Your hamsters cage should
contain an exercise wheel. In the wild hamsters have to travel long distance
to find food, so you have to make up for that with an exercise wheel. For your
convenience all of our hamster cages come with exercise wheels. It is important
that you let your hamster out of its cage for exercise, but you also need to
keep them safe. That is why we recommend playpens, available here.
