Question, always a question... I found presumably a mast cell tumor behind the front leg of my 3 1/2 year old ferret. Temp and everything else seems normal. I have made the earliest appointment with my vet. She has seen a lot of ferrets, but does not know what the incidence of recurrence is in animals that have early removal of the first lesion. Any input? Amy Cada [Posted in FML issue 1085]
