I have also had hamsters. One of them I made a mistake of putting it on my cousin and she got scared, threw it and it's back legs like broke or something. It lived one week after that and died. The other one I had called Acrobat would climb out the cage EVERY night, and my mom would forget and think it was a mouse when it climbed on her bed and threw it. It would be fine though but it would do that every night so just remember to get a cage with no door or a door that it can't open because they are very smart at escaping and lifting up doors. Also you need that paper material for bedding, I don't know what it's called. They like to hide under that. And yes they do bite when they get scared so tell your kids never to wake them up with their fingers. And they like to reproduce

alot, and sometimes eat their babies
