I got my female JCP in February of this year. 4-5 feet long. She ate the week after I got her, and the following week. Both times F/T small rats. That was the last time she ate...early March. She has not eaten in 7 months. She's in a large Repti Rack cage, around 4x2x2 with a fluorescent light set on a timer for 12 hr on/12 hr off. She has a hide. Driftwood. Fake plants. Aspen substrate. UTH on a thermostat set to 90. I don't know what this snake's problem is. She's worse than any ball python I've had. When I first got her she had cypress mulch substrate and a small water bowl. That was IT. The only thing I've changed is the subrate because the cypress was getting moldy. I've tried live, F/T and prekilled rats and mice. During the day and at night. Left a F/T in overnight. No interest at all. The only thing I can think of to do is stick her in a tub. Maybe she's stressed from too much space? But the guy I got her from had her in the cage for months. She hasn't grown at all. I would say she's a little thin, but not emaciated looking. It just sucks because she was supposed to be my "display" snake. My BPs are in a rack. Could the substrate change cause it? Has anyone had this problem?
