Do pets mice bite and if yes how can I choose one that doesn't bite when I handle it?
they bite only if provoked or poorly socialized! when you buy a mouse it should be friendly, moderately active and not hide. if it comes to your hand that's great. beware of too hyper or lethargic mice coz those can be ill.
When I was a kid we had 2 mice and no one of them ever bit me. My parents would always supervise us when I handled them!
