Weird behavior maybe?

This is likely why you're having problems with her fasting. She's not a corn snake. They need higher temperatures to be able to digest properly and if they don't think they will be able to maintain proper body temps, then they won't eat. I keep mine at 94-95 on the hot side and 82-85 on the cool side(room temp is 84 usually). They eat, they don't fast in winter(even breeder males), and they growgrowgrow. Termite mounds are quite warm, as are burrows under the ground, blacktop roads at night.

A good number of larger breeders just keep their rooms heated to 88/90 without any supplemental heat. The snakes thrive, which is all that matters.

My snake isn't fasting. She's eating, shedding, pooping perfectly. I don't know where you got that idea from.

Either way, those temperatures are too low, they originate in grassland, woody, and savannah-like climates in Africa with much higher temperatures all year round.
When it does get a bit colder, they go underground, where things usually stay pretty warm and snug in burrows. :]
85-90 is ok for the warm side if shes not having problems but anything in the seventies is much too low for a ball python.

To the OP: Try lowering the cage heat a bit and see how she reacts. If she shows any interesting reactions let us know, if she goes back to normal and hides and such, maybe keep her high side between 88-90. :]
