I have a ferret the same one who is recovering from ECE. Before we found he had lost weight due to ECE we were thinking that he may be developing adrenal disease. During surgery to learn why he was losing weight our vet found an enlarged left adrenal gland and removed it. The reason we thought he may be developing adrenal disease because he was showing aggression toward one of the other ferrets (he was starting to expand it to his cage mates by the time he had surgery). The aggression was once every day or so he would attack this one ferret fairly aggressively. Now that surgery is over (about a month ago) and he is getting his strength and some of his weight back (about 5 - 6 ounces) and is beginning to play and even look pretty happy (open mouth swinging head back and forth (only once so far)). He again attacked the little girl again. My question (finally) is how long before the hormone level drops and he goes back to being less aggressive? Thank you Mike [Posted in FML 6653]
