I have a hamster and I fell sorry for her because she's alone all the time. I think about getting her a "room mate" (or should I say cage mate) I'm not getting a male hamster because I don't want a bunch of baby hamsters. I thought about getting another female hamster but I'm not sure if they fight. I know that male hamsters fight but I'm not sure about females. I also consider getting a mouse. I have no idea what hamsters and mice are like with each other. Please let me know if you know anything.
