We just got our boy yesterday, and I tried to hand feed him, which was a huge mistake. He’s already bitten and drawn blood. The pet store said they had a lot of problems with him too and that he often would bite them as well. I don’t want to give up on him, but I can’t have an aggressive rat because I’m not sure what to do with them if they are biters. Does anyone have any ideas? I’m not sure if I should give him a few more days to get acclimated and then try the holding him with a towel method?
