My first ball python was quite skinny, so I put him on a 4 day feeding schedule for about 2 months, he is now on a regular 7 day feeding schedule with the rest of them. I now feed 3/4 snakes once every 7 days (weaned rats....all between 300-400 grams) and my little female is on a once every 4-5 days feeding schedule (adult mice, she's only about 110-120 grams). Feeding every other day is way too often and doesn't give them any time to digest what they ate. Like others have mentioned, I'd check your prey size...they shouldn't be hungry enough to eat every other day. Mine eat their weaned rats and then I don't see them for 2 or 3 days because they are so stuffed lol.
