should i be worried?

ok so my bp hasnt taken a meal so far in 3 weeks. should be worried about her health? shes on f/t and im going to try a rat pup soon

I wouldn't worry since ball pythons fast all the time...My 290 gram ball python didn't eat for a month and actually gained weight instead of losing it... who knows, she just might not be hungry... but just in case, try covering the sides of its cage with dark non-see through material.That should help her if she might be stressed out. Pics of your setup and temp and humidity readings might help.

the temps are perfect except when i wake up in the morning they drop to 85, humity is at 50% and half of the back is covered cuz i ran out of black paper.
