You can,t overfeed a ball python. I got my male BP just a month before i got my BCI. He was 3 years old. I was totally a beginner when i got him and i did overfeed him. As a result he stopped eating 8 months and started after that to eat again. I am beginning to believe that you can,t overfeed any snake in normal ways. My dumerils boa ate last time before 3 weeks. I offered him a rat yesterday and he does not want to eat. I guess his body does not require food now and he knows it. My BCI showed no interest in that rat again. So i,m going to give him a two weeks pause before i feed him again. So they know if their bodies require food or not
