To Chris and Carla concerning cardiomyopathy: I am sorry for your recent losses. Last night I tried to find a copy of an article I wrote several months ago for the FML on CMP, but it seems to have departed my disk. But I believe you can get it from the FAQ, or CARDIO DISEASES, as Judy said a few days ago. In short, CMP is a congenital problem in some lines of ferrets that manifests as ferrets get older. CMP means that the muscle of the heart becomes progressively weaker, and the heart is no longer strong enough to pump all of the blood. ASt he muscle weekens, it stretchess, and the heart gradulaay enlarges, sort of like a balloon. As the blood begins to back up, it will accumulate fboth within the lung and around the lung (often also in the abdominal cavity), resulting in coughing, which is the most commonly noticed sign. Actually, msot animals have decreases in activity first, as they tire easily. The fact that your pet only coughed for about a week prior to its death is unusual. CMP can be treated with some drugs, including diuretics which help it manage the load, but the damage is progressive and cannot be reversed. Once again, I am sorry for your loss.
