I have a question for the vets and breeders on the list; or anyone who has had experience with cardiomyopathy in ferrets for that matter. In Oct. I lost my hob, Axel, when he had a heart attack during surgery. His father and half brother have both been diagnosed with cardiomyopathy since his death. I have Axel's granddaughter, Peanut, and his great grandson, Lionel. A friend of mine has his grandson, Freight Train. Freight Train and Peanut have been used for breeding and I would like to use Lionel, but we were wondering what the heritability for cardiomyopathy in ferrets is. Peanut recently had a litter and my vet said that I shouldn't worry about the kits having heart problems that they are probably far enough down the line to be safe. But she also mentioned that not a lot is know about the heritability of cardiomyopathy. All three of these ferrets have exceptional conformation and temperment and I would like to continue breeding them but I am worried about passing on the disease. I have also heard that it seems to strike the males more than the females. I would appreciate all information on heritability that anyone can give me. I would like to hear from anyone else who has had ferrets with this disease and whether or not it is passed on to the kits and how often. Thanks! Cindy [Posted in FML issue 1467]
