What is the difference betwixt a gerbil and a hampster?
I think it's the tail!
Gerbils like to live in groups and one may be unhappy if it is living alone. A hamster is fine living alone and doesn't need any companionship. In both cases, if you are going to have two of either, choose two males. The females of each are very aggressive with each other. A male gerbil in particular loves the companionship of another male. The male hamster can either me happy by itself or with another male hamster. Just don't put two females of either together.
Well ain't that always the way?
Looks to me like a gerbil is just a little rat!
Did you go to the rodeo yet? If so how was it?
