I got a new BP on 6/5 and he’s had two meals(small mice, will be switching to appropriately sized rats as soon as my supply is gone)with me since coming home. Over the past week or so he’s been looking way too thin to me? I messaged his breeder and he said he was born last September or October. When I got him, I weighed him about a week later and he weighed 127g. Weighed him a few days ago and he was 139g. He’s active and has only refused one meal since he arrived. Not sure what’s up. Any advice to get him looking a little better?
