A few months back I rescued two ball pythons from my sister's friend. They were kept together in a filthy 30 gal tall with no substrate, hides, heat, or humidity. One was 2 1/2 and the other was a yearling. The older one was sick, but after a vet visit he is doing much better. The yearling is as small as a hatching. She wasn't sick (surprisingly). When I separated them I kept her in a tub, I recently upgraded her tank back to that 30 gal tall and moved the older one into a 40 gal breeder. The yearling has been regurgitating her meals after I moved her into her tank. I waiting a couple weeks before I feed her because she is a easily stressed snake. She still does not like being handled, flinches every time you walk past the tank. I honestly see no hope for her seeing as I've had her for a good amount of time and still hasn't come around one bit. I'm contemplating putting her down. I see no point in rehoming her, I've done everything I can. What should I do?
