To Jason Creager - Jason - you have two options now, if you are convinced that it is an adrenal tumor. You can operate, or you can not operate. If your ferret is not a surgical risk, then he can live out the rest of his days (although they may be shortened) with some less hair. But if you can have the surgery done, it will be a great benefit. I have doen two of mine, one at 4 and one at 6 within the last 18 months, and I ahve another 4-year old I need to do in the next couple of weeks. If you don't do the surgery, you can expect addritional hair loss, some weight loss, and lethargy. The tumors generally aren't life threatening, except in the case of very aggressive malignancies, but they will decrease quality of life.
