The age old question... "why won't my ball python eat?"

Have you changed anything in the vive set-up lately?
What are the temps at, and how are you measuring and controlling them?
What weight is your BP? What size/weight prey do you offer it?
How do you offer it?

Soooo many possible reasons for a BP to go off feeding. There are a TONNE of threads out there just like this do a little searching around with the search bar at the top right corner of the page, read some other threads, and you might find your answer quickly. It could be a very simply fix! Or, it could be a stubborn ball python.

Best of luck!
