I used rescue WC bps back in the '90's. They ARE a PITA. Everyone I rescued had mites and sores where live food was thrown in their cages and they didn't eat. Some had cases of mouth or scale rot. None ate for me for months it seemed. They're very skittish and will ball up at everything unfamiliar to them which makes it difficult to treat them.

WC demands alot of time and patience. They can be very rewarding animals, but not for an inexperienced keeper.
