Thanks. I'll check for mites, but not today -- since she just ate. (If it is, I'd be surprised, because I just had her out two days ago and checked her face, throat, and underbody. I didn't see anything.)
The cool hide (the one she likes the best) is a nice tight one, it's a plastic to-go food container.

I'll swap out the other two -- they are the ones that look like half logs (Zoo Med habba hut). They definitely do not fit her like a turtle shell.
And, I'll get her the larger mice for food.
I don't think it is heat, though, do you? I monitor the temps carefully and keep everything within range and double-check with the temperature gun to be sure.
Thank you for taking the time to help!! I appreciate it.
