I have a ferret "Lydia" who is about four being treated for adrenal disease. (One removed and one still overactive.) Thanks to all who responded with advice. No one, however, told me what the life span is on medication. I know it varies between babies but a general estimate would be nice. Right now I am using a ferret food made by Mazuri which is apparently a Zoo supplier. Has anyone heard anything about it? [Posted in FML issue 1914]
