I hope it's nothing that can't be fixed with proper husbandry & some "TLC".
I totally agree with Zincubus...hydration is more important than food right now- without that, she either won't eat or be able to digest it if she does.
Pinkies are too small, of course...I'd follow Zincubus' directions, offer f/t first...& a live fuzzy only as last resort.
How long before you get a thermostat? She still needs proper temperature options. (I'm sure you know that).
Hope that her discounted price makes up for her issues & that all goes well for you...it's so hard to ignore animals suffering, even when it feeds the system.
edit: I see you've already arrived at a temporary solution for the thermostat.Wishing you & snake the very best of luck.
