Just to put this in perspective. I have a female pastel ball python adult that has not eaten since the middle of November. She was around 1500 grams when she stopped, and since then has shed once and is about to shed again. I weighed her last week and she weighs 1420 grams....so after about 4 months with no food she lost only 80 grams.. . Most of that is probably just poop. So as long as your snake is healthy she can go a very long time without eat, and for many bps this is normal in the winter and early spring.just make sure her cage temps are within the correct limits and that she has plenty of water and a secure place to hide and she should start eating again.
