She’s a BEL, so I can see that she doesn’t have mites. She’s currently on paper towels as well. She pooped just yesterday (as she usually does only when she’s finished shed) and her stool
looks good and normal.

The folds are like almost inverted cracks and they are quite prominent. There are also a lot
or them, almost like one of those wrinkly English bulldogs, which yes appears to be dehydration. Maybe I will get another hygrometer but it seems accurate as it matches the humidity of the weather app when i leave it outside. I think I will give her a humid hide as you suggested. I was planning on doing that when I moved her out her tub and into her wooden vivarium next week - but now that she is “sick”, I will have to keep her in here until she seems better. Parasites seem like the only
logical option, I’ve also heard of just generally bad sheds for no reason in ball python younger years, how credible is this? It still wouldn’t explain her dehydration
