It worked for us. In early January we had adrenal surgery performed on our 3 year old white female. Progress since then has been remarkable to say the least. Within two weeks she had regained nearly all of her hair. Its now been about 5 weeks since surgery and I'm pleased to report: 1. After turning an initial, very attractive, golden honey color, she has now got as thick a coat as I've ever seen on her. Snow white. Looks more like a polar bear than a ferret. 2. Her weight is up 2 ounces from its previous highest record. 3. Her energy and activity is the way she was when she was 6 months old. Nips (not objectionably hard) anyone who attempts to prevent her getting her own way and is attempting a take over from our male regarding who's king of roost. 4. No scar left. My thanks to one of our regular corresponding vets who performed the surgery. [Posted in FML issue 1480]
