The little sand boa with the lump is still doing quite well, but has developed another strange symptom. Her skin is baggy, almost like its a size too big for her. It feels nice and healthy, and I have no reason to believe she's dehydrated. At any rate, she doesn't drink when dunked in the water dish. Neither of the other two sandboas we went through the same non-eating rigamarole with and which have had the exact same feeding schedule have the same thing. She's gaining weight pretty much as expected. We noticed this when we first brought her to the vet and now it's just more pronounced. I can post a pic if necessary. Any advice?
