I got a nice female in a trade that hadn't eaten in (according to previous owner) about a year. We both suspect she was WC. A vet visit showed nothing physically wrong. I tried all sorts of prey items. Live, PK, FT, rats, mice, soft furs.. Nothing. Today I got a gerbil for her, and that did the trick. I'll give her a week or so to digest that, they try starting her on some rat pups rubbed with gerbil bedding.
