Coughing is not caused by adrenal problems (except sometimes when too much fur is ingested in grooming but it is not a symptom with which one normally thinks of adrenal neoplasia) and the coughing is a more immediate concern because of risk of cardiomyopathy or of serious lung infection -- either of which needs to be tackled in a timely fashion with specific treatments -- than for typical adrenal growths, but since this one is having discomfort problems (the sores) and since there is also a risk of more serious complications for adrenal neoplasia vet care is needed rapidly. If you look in the Critical References section at http://www.ferretcongress.org (a resource everyone should bookmark because the links are superb for many ferret health, behavior, care, and legislation questions) you will note that one section is devoted to finding vets. The listings given each differ from the last, but you will find that each is a marvelous resource. [Posted in FML issue 4280]
