My young BP is still not eating, and I'm beginning to get worried. She's acting normal; sitting in one spot during the day and moving about at night. She has been passing urates, and poo as well until she stopped eating. For the first two or three weeks I had her, she ate one small fuzzy rat per week, then about a month ago she stopped taking food.
I wouldn't normally worry, but I can tell she's beginning to drop a bit of weight.

She's in a 20 gallon sterlite tub with holes drilled in the sides, and a heat pad on the bottom with a thermostat attached. Her temp gradient goes from about 83 to 90, with places to hide in both hot and cool areas. Her humidity is 50-60%. The bedding is cyprus mulch, and she has a little sphagnum moss in one of the hides.

Any suggestions as to what could be going on? I can't think of anything wrong with her settings... I know it's not weird for pythons to go off food, but she's still growing (probably between 6-8 months old) and I don't like that I can see her starting to get thinner.
