I've got a (what I believe to be) full grown male ball python. He's right at 4 feet long. When I first got him he would eat every 2 weeks, then it went to 3 weeks, then to 4 weeks, but now he hasn't eaten in 6 weeks. I'm giving him white female rats (same as he has always eaten) smaller than the thickest part of his body. The warm side of his tank stay right around 90-94 fahrenheit. His tank stays in a room that has VERY little traffic. The room stays darker, but not pitch black. Need advice on getting him to eat. Thanks in advance.
