A small rodent not to be confused with a mouse. They are very fuzzy and friendly. They also like to dance. Also, they will run in little plastic or metal wheels until they die from either heart attack or exhaustion. Make good pets except they are known to plan world domination, escape artists and also like to run around your house and poop everywhere.
