I have a mouse question. Can you help me?

I own rats, so I'm not quite as sure about mice. What I DO know is that if you are afriad of them getting overweight, buy an exersice wheel for them. I hear mice love them. There are a good selection of them at petco and petsmart. The only downside is that cetain ones(not all but a good deal ) squeak and it can be frustrating during thenight.
