Ball python excessive soaking; help?

[Sita]

The two main reasons for soaking are too high of temperature and mites. If you are certain the warm side is about 90, using either an infrared temp gun or a digital thermometer probe, NOT an analog dial thermometer, then switch the substrate to paper towels for a week and look for an tiny "pepper" bits on it. You can also see them in the water bowl sometimes as they drown and fall off. Make sure you wait two days after feeding before handling through.

If her new cage is a lot bigger than the old one, and it has just the two hides and the water bowl, add some clutter to make it seem smaller for now. You can use more hides, crumpled up newspaper, decorative vines (make sure they don't have any rings or sharp bits), etc. Even though she's a year, she may still be feeling insecure from the extra space.

I would give her at least a week to settle in after changing things. Soaking in and of itself is not going to hurt her, but you need to figure out why she's doing it, as those things are stresses to her.
