Thanks to everyone who gave me info & advice on both the TN panel and using the des implant for adrenal disease prevention. There are a few things I should make clear. 1. At this time Spooky has no signs of adrenal disease, unless you consider his yellowish color a sign. He has a very thick coat, no urination problems, weakness, etc. 2. Every vet in my area, which is an FFZ, charges $225 for the TN panel. 3. My current vet has had the most experience with ferrets in my area because he has lived in CA (where he said there were lots of ferrets despite it being an FFZ) and Canada. I've been to just about every other vet; most have seen very few ferrets because they began practicing after the ban on ferrets was imposed. A few of them made some very serious mistakes that cost the life of my ferrets. And since I've been to all of them, I don't have the option of going to another vet. In addition, my current vet is charges half the cost (except for the TN panel) of all the other vets because he works for the Humane Society and all others are private vets. 4. When he referred to possible side effects, he was talking about the possibility of long-term side effects from giving hormones. There are no long-term studies as of yet, as far as I know, since the implant has only been used for a short time, especially in the U.S. I am wondering if any one has had the experience of their ferret's hair falling out AFTER putting in the implant. This happened with my Minky. How likely is it that it's just a coincidence? Thank you Sukie for the info on how the vet can order the TN panel directly online. I sent him this info along with the fee schedule. I have not yet decided what I'm going to do, but I'm not planning to do anything before Spring. Wishing good health to all and their furkids in this new year. Shron Spooky & Xena Missing Rocky, Minky & Klondike [Posted in FML 7665]
