To Mary from Peoria: >Both of these ferrets have been to the doctor about the hair loss. He said >if it was adrenal, it would probibly have started at the base of the tail >and then forward from that. One thing I have learned over the years is that a lot of animals don't read either the books, or the FML. Look at the pattern of the hair loss, not the pattern of development. If there is a question, the adrenal panel from UT may help, but I think that I would probably do the surgery, at least on the one with the profound patchy hair loss.
