Update:

Sally was in her warm hide this evening and her head kept poking out. Must have been the live mouse that was on top of her house for 3 hours. I pulled the plants and cold hide out so it had nowhere to hide and put it in. 30 seconds later, she struck and coiled. I guess the fast is over now that she has what she wants. Planning on getting a few feeds down her and then trying to transition to f/t again. At least I know she'll eat, and that's a relief.
