Hi everyone! I finally got the implants last month for both ferrets. The cost for each ferret was $350, including exam; no anesthesia used. My question is: how do you know if it's working, other than doing the hormone panel from TN? The only signs of adrenal disease is Minky's coat is very thin and tail somewhat bare; Klondike's fur, which should be white, is yellowy- orange on his back. The color of Klondike's fur was what made me suspicious that he had adrenal disease, as I remember someone writing about this here. Both were confirmed with TN hormone panel. Will Minky's fur get thicker and Klondike's become white? Or is the only way to know to do another TN panel in the future? Also, assuming it is working, how long does it last? I've read here anywhere from 6 to 20 months. Thanks for any info and have a great holiday. Shron Minky & Klondike Missing angel Rocky [Posted in FML 7077]
