Last night Molly shed, the first time since I have owned her. I tried to keep the humidity high, and do everything right. Her shed came off in what I believe to e 1 piece. Except now she has what appears to be a small piece of skin at the end of her tail. It looks like a piece of thread tied around the last 1 mm of her tail. I thought about using a wet sponge to wipe it off. Anybody have this happen to them? If so what did you do?
