Ball python won't eat

[PghBall]

Well she is having a curved cork and a cave, I have heard about identical hide issue, but she was completely fine at the beginning with them. Also the other thing, she actually refused her meal when she had her old enclosure setting (when I offered small rat), after that I have noticed she got mites on her and changed it over to paper towel and cardboard hides just to treat it, after a week I have changed it to her old setting. I wanted to inform about this as maybe that played some big role in her fast.
I'll try to regulate the temperatures and then see how she go.

The stress from mites, changing her environment could definitely have something to do with it. Definitely work on regulating your temps and keep offering every week. Hopefully she'll come back around for you.
