(bhw) While excessive doses of prednisone, or lower doses given over moths or years can result in hair loss in traditional domestic species - this is extremely rare in ferrets. They are quite resistant to the prolonged effects of prednisone, although I suspect if you gave enough pred for a long enough period, you could induce a cushingoid syndrome, with its resultant alopecia. But I strongly agree with Dr. Purcell here - adrenal disease is by far the more likely possibility. >>In case it is adrenal disease, what are the treatment options for an 8 >>year old ferret with insulinoma and adrenal disease?

Actually, you are asking us to guess here as well. It is exceedingly difficult to assess surgical candidacy of a ferret online - chronological age is generally not a factor. If there is no evidence of heart or renal disease, if the glucose is well regulated, and the vet is a good surgeon and anesthetist - surgery may well be an option. I do see a worrisome trend, though, but not unexpected - people tend to rely on medical therapy knowing that the treatment does not reduce the size or growth of adrenal tumors, but simply blocks the effects of the estrogen. However, if medical therapy is considered to be the best option, then Lysodren is really not a consideration. The effects of Lysodren are unpredictable - the same dosage could do nothing in one ferret, and wipe out the adrenals in another (although it is more likely that it will do nothing.) Lupron is safe, and effective in hair regrowth, and to a smaller extent, reversing some of the lethargy associated with the adrenal disease. With kindest regards, Bruce H.
