Female BP still hasnt eaten

M female BP hasnt eaten normally since January or February. I offer her a thawed small rat every other week and she wont take it. She just turns her head and goes back into her hide. Temps are 87-88 and humidity is 40-50

Are you able to try live prey? I would see if you can get her at least eating again by offering live then try switching her back to f/t in the future.

Is that temp ambient or hot spot? Humidity is a little low. How are you measuring temps and humidity? Pic of setup?

They are incredibly temperamental creatures at times. My baby female is tiny compared to how big she ideally would be for her age, due to the fact she is a nightmare to feed. She recently fasted for 3 months straight, wouldn't go near the rat I was trying. Then, this Saturday she struck without hesitation... Nothing changed in her set up, she just wanted to feed. That is how they work. If their setup is okay, then she will probably eat on her own terms when she wants to.

Just keep trying. She'll eat when she's hungry
