Mouse or hamster for a pet?

You should get a hamster, mice die relatively quickly because they have a short life span. Mice are dirty and chew on things if they get out. Also, mice are almost impossible to find if they get out of their cage (trust me if you keep an animal in a water tank or cage you will bound to let it out sometime on accident). hamsters are much easier to find, they chew also but not as badly as mice, and its more of a pet than a mouse. Just remember whichever one you get they will both bit equally the same it depends on their personality and how scared they get, usually mice will bit more.
