I've got a ball python that I believe is under a year old. I got him last Christmas. He's been eating frozen thawed mice very well but he is under weight. I tried to switch him to rats but when I offer it to him he's not interested in it at all. He just seems scared of it. I tried using rats that were the same size as the mice, I tried scenting the rat, I tried braining it, and I waitied 5 days before offering it to him again. He doesn't seem the least bit interested in rats and he will gladly take a mouce. Once he bit the rat thinking it was a mouce but he freaked out when he realized that it wasn't. Most people say that the only way to get ball pythons too switch to rats is to keep trying but he's pretty young and he loses weight pretty fast. I honestly have no clue what to do. Is there any way I can get his weight up by feeding him mice? I've been offering him a second mouce after the first and he looks at it and smells it but then doesn't take it. Also Iv'e heard that feeding your snake too frequently can be very bad for their health. Can I please get some advice on what to do?
