I have a copy of Debra Jean's book. I am confused by the chapter on ferret health. There are several 'clusters' of symptoms listed. I must be blind or something, but I don't see any definition or remarks about causes of the clustered symptoms. For example, the symptoms might be 'hair loss/over eating/excessive drinking/change in activity level' but there would be no heading to say "adrenal disease" or "could be adrenal disease or insulinoma or yada yada yada" with some recommendations for first aid and treatments that might be had from the vet. I guess if there were such definitions or remarks that people would take a very sick ferret to the vet, and scream at the vet about treating the ferret for X problem, without allowing the vet to do a proper exam and diagnosis. I little knowledge can be dangerous... It is also true that I don't have the latest addition... comments anyone? A. [Posted in FML issue 1814]
