Today I got a rescued normal ball python from a guy who rescued it. When he rescued it he said it was only as thick as a corn snake, he has kept it for a month to get some weight on it and it has gotten thicker. The ball is around 3 feet long and around an inch and a half thick. Will not take small rats and it should at this stage only large mice ft. Have put it in a proper terrerium under heat lamps and a UV light with alot of water for hydration. What is the safest way to put weight on this poor guy? Should I feed it every 3 days . This little guy except for being too thin looks quite heathy otherwise. Any advice would help thanks Until I see him have his first shed with me will I be worried. At least then I'll know he is putting on the weight.
