Bleh! I don't like petco much, with the exception of one store in our area. I was checking out hamsters, since ours went to hamster heaven. (My daughter was SO sad about it I was looking to maybe replace her, but was trying to find a nice one) I pulled out 4 hamsters with open sores. Yuck! Having sad all that, I would advise looking at them. Is the cage clean? Is there enough food? If yes, then it would probably be ok. Not the best solution, but will work in a pinch.
