Not feeding... perhaps a little overcautious?

So I recently moved my bp to a warmer room to raise her ambient temps.
I also purchased a CHE to warm things up, as my house is naturally set very
cool. Her UTH is set at 93F, the cool side (with the CHE) is at about 75F. Humidity is at 60%, give or take a few. The ambient temp on the hot side may not be as warm as the cool side, but the UTH is nice and warm. Anyway...

She ate after the first week I got her. Didn't eat the next week, and about 5 days later, still no luck. Is two weeks a time where I should be worrying? She's an '09 normal, weighs in at about 600g. New(ish) owner, just a little worried! Thanks for your help!

Could be going into a winter fast

I wouldn't worry at two weeks. She's just being a ball python. She may skip a meal here or there, or, as the previous poster mentioned, she could be entering a winter fast. Monitor her weight, but don't stress.

How long do they usually fast for in the winter?

Depends on the animal, ive had them fast as long as 9-11 months in the past

Simply moving a BP from one room to another can be enough to lead to a refusal or two.

The important things here is that your animal is old enough and has a good body weight to endure a few skip meals or even a fast.

If your setup is optimal another thing you can try to do is limit your handling for the moment being.

Make sure to monitor your BP making sure it is well hydrated and simply wait it out, it knows how to eat and sooner or later will resume feeding.
