My Mr. B. suffered from the very same symptoms as your Kedi. He too spent several days in the "incubator" at a critical care facitlity after suffering complete respiratory arrest. At first, they thought he might be suffering from cardio myopathy, a serious but not uncommon heart condition seen in kitties. He had already been diagnosed with asthma. (Your Kedi's symptoms sound very much like asthma.) Cardio myopathy in Mr. B was ruled out, though they did find some cardiac irregularities. (Slight heart enlargement and a valve problem) He was on some pretty potent cardiac drugs for a while, then weaned off them. For 5 years now he has been asympomatic, though we still watch and treat him for asthmatic episodes. My best advice would be to wait and see until the specialist has examined him. What cardiac problems did your vet diagnose? Did he give you a name?? Do you know what tests were done? A cardiogram, chest xray and ultrasound are the tests most commonly done when diagnosing heart conditions in cats. I know how very frightenend you must be. I certainly was. But, there are so many heart conditions that can be treated with medications. Until you get a definite diagnosis, try to think positive thoughts. I know I will be praying with all my might that your precious baby Kedi will come through this OK. You sound like a very special, very loving kitty Mom. Kedi is lucky to have you watching over him. Please let me know if you have any more specific info. on what your vet has already diagnosed. Maybe then we can talk more about what they may do to treat this. All paws at my house are crossed, and tonight, extra special prayers will be said for Kedi. Love and good wishes to you and dear Kedi. Fondly, Sandra, Mr. B and Oliver
