I bought a ball python from a breeder that hatched at the beginning of October. He weighed 30 grams when I got him and has gained 13 grams during the month I've owned him. I haven't been able to find much information on young ball python weight in the first few months of their lives except for a weight chart that had the hatchlings at 60 grams. I've been feeding him every five-seven days depending on when Mr. Stubborn wants to eat. He is around a foot long and is more triangular than round which makes believe he is underweight. The breeder told me she'd fed him three times before I got him, but I don't know if that's true. I'm hoping someone could give me better information on what he should weigh or if he is fine.
