Loki is a three year old male ball python. The breeder told me that he'd been feeding him small rats, so that's what I've been feeding him. But I notice that he kinda keeps looking around, as if he's still hungry? I just finished the pack of small rats, so I'm torn between getting more small or getting a pack of medium. I know the rule of thumb is food the size of the fattest part of their body, but Loki is very skinny. Not underweight, no hanging skin or anything, just very thin. So I wonder if a medium would help him fatten up just a little? On the flip side, I've read controversy about feeding two rats in one feeding.
What should I do?
