Well, the symptoms that you relate may be the early signs of adrenal
disease, but there are far more ferrets who simply are aggressive
toward other ferrets on general principle than because of an
elaboration of estrogen or testosterone due to adrenal disease.
The rat tail sign may simply be a sign of stress - a ferret who is in
constant battle with other ferrets would certainly be under stress.
REgarding testing protocols for adrenal disease, the adrenal panel
(provided it is the one available at the University of Tennessee is
far better for identifying adrenal disease in ferrets. It is
approximately 95% predictive, with few false positives. Ultrasound
is a poor choice, as many ferrets may have estrogen-secreting lesions
that are not large enough to cause an increase in the size of the
adrenal gland, which is required to make an ultrasound diagnosis.
Personally, I believe that ultrasound rarely contributes
significantly to diagnosis in adrenal disease in the ferret.
