I've bred rabbits and hamsters before but rats so far have taken the cake. My first prego rat gave birth this morning but she's such a bad mom. Sure it's her first time but gez. I culled 10 some babies( she was huge!)left her with 5 but she has no idea what to do with them. She feeds them but constantly scatters them. she'll just move one and forget about it until it crys. she steps all over them and has bitten a few of them. Hopefully the few left will make it to size.
