While your male who is attacking the female very well could be adrenal, don't forget that it could be the other way around as well. Often, when a ferret is being singled out, such as your female, it means that she could be adrenal as well. I once adopted a male out to a family with an older female. She had brought her female here and they got along beautifully. The lady brought the male back in a few days, my only failed adoption ever. It seems he had attacked the female to the point that she had to have stitches!! I was appalled that this happened, and told her to have her female checked out for adrenal. Sure enough, that was the problem. I adopted the male to another home and it never happened again. Katharine Florida [Posted in FML 6618]
