I have a 4.5 yo sprite who sometimes wheezes when she sleeps. She's a bit overweight and I thought that probably was the cause. Chest x-rays showed what my vet called "increased interstitial pattern". She said her lungs looked like the lungs of an asthmatic cat. Have any of you had any experience with allergic bronchitis or asthma is ferrets? How common is it and what is the best treatment? Secondly, all the ferrets I've known or heard of that had cardiomyopathy were all males. My vet said that cardiomyopathy is predominantly a male disorder. How common is it in females? Can a female be a "carrier"? Would she carry a recessive gene for cardiomyopathy that would make it possible for her male offspring to develop the disease if dad also has the gene? Thanks for any information you can give me! Cindy [Posted in FML issue 1565]
