Ok this is getting quite frustrating/worrisome. I have a 2yo bp that is on his second fast. His first was 6 months, and I snapped him out of it with live mice. Now, his last meal was Aug 29/07. He won't eat p/k, f/t, live, nothing. I realize that it's normal for them to fast, but he's not nearly the size he should be for his age and he's not just some snake, he's my baby. He's had one or two sheds in that time, and all else seems normal. I just want him to eat again. I've tried everything I can think of. He's starting to look quite thin, and I'm beginning to see his spine now. He's never looked like this before. Is there anything I can do?

fyi, he's got a recent clean bill of health from my herp vet.
