Took a chance and temporarily screwed myself LOL
Didn't have any rat pups on hand (he's a bit too small for weaned) so I fed this guy f/t adult mice for a few feedings. Finally got my f/t rat pups in (what he was on before) and sure enough, he doesn't want anything to do with them and wants his mice. Dang-it! Oh well, I'll get him back over on the rats soon enough, not worried about it, it's just annoying.
Also, he came in a bit dry and sure enough had a terrible first shed here, a few hour long sits on some warm wet towels and was able to get it off him but he is not liking me much now. Little stinky mouse eating booper! I love him so.
