Pulmonary edema is the buildup of fluid in the within these air sacs leading to shortness of breath. Located in the lungs are thousands of air sacs (alveoli) which are small balloon-like structures where the exchange of carbon dioxide and oxygen occurs. Tiny capillaries surround the alveoli on the outside. When the cat breathes in, air enters the lungs, causing the alveoli to expand. Oxygen passes from the alveoli and into the capillaries, carbon dioxide from the capillaries pass into the alveoli and is exhaled out. The most common causes of pulmonary edema relate to problems with the heart, such as hypertrophic cardiomyopathy. Heart diseases can lead to reduced movement of blood through the capillaries in the lungs. As the blood flow slows, fluid leaks out of the vessels into the airways. 
All cats have something special about them that catches the eye. Some have lots of soft, gorgeous fur. Others have almost no fur at all. Some refuse to be ignored, and will draw your attention with loud meows, chirps, or will cut to the chase and put a tail in your face! These cats are remarkable for their size. If you’re looking up world records for cats, you’re likely to see one of these breeds with the prize for size!
Last, but maybe most important is, if you can pay to see wild cats on your terms (ie: cheaply, in a cage, or being forced to let you touch them and have your photo with them or their young) then you aren’t learning anything about who these animals really are. You aren’t learning about how they fit into a complex environment when they are housed in a situation that does not duplicate all of the web of life that they are a part of in the wild. All wild cats roam territories that are calculated in miles, not square feet. To know anything about them, you have to see who they are in their real environment.
Hello there! My girlfriend and I have an exclusively outdoor cat who has recently shown some worrisome behavior. Typically, Simba is very independent. Only allows some human interaction when we feed him, and even then it's more like we have to sneak a pet here and there. About three days ago I came home and noticed his breathing was fairly rapid. I thought maybe he just came to our porch after some activity, so I mentioned it to my girlfriend in passing. Yesterday she called me at work worried. Simba was letting her pet him and even came into our garage (which is basically set up like a living room. There's a heater, ac unit, tv, carpets, etc.) It's very home-y. Anyway, he's been in the garage the past two nights since its been in the thirties at night time. He lays very still, breathes very rapid and heavy. I can hear, what I think is congestion as he breathes. He hasn't eaten or drank much. The only thing I have gotten to eat are a few cat treats. I read online we could give him a small dosage of benedryl. But I don't want to give him anything that would essentially hurt him. He also has random asthma like episodes. Wheezing and coughing with his mouth closed. He meows when we talk to him, or look at him. Part of me feels like he's asking for help! Unsure if whatever he has is life threatening or just a little kitty cold.
Example a amazing Maine Coon can cost $1,200 (Parents HCM tested, fixed, shots, everything!) compared to a sickly Maine Coon (Parents not tested, no shots, not fixed and not pretty) post on a classified site that is $500. Some people blame the kitten mills, but the person to blame is some one funding those places. You can do the research, you can pick some one upholding proper ethics.
If your cat is having difficulty breathing, this can be a life threatening emergency. It is important to have your cat seen by a veterinarian as soon as possible. You will need to give a thorough history of your cat's health, onset of symptoms, and possible incidents that might have preceded this condition. During the examination, the veterinarian will carefully observe how your cat breathes, and will listen to its chest for evidence of a heart murmur or fluid in the lungs. Your cat's gum color will be carefully evaluated as well, since the color of the gums can indicate whether oxygen is being delivered to the organs (hypoxemia) effectively, or if it there is a low red blood cell count (anemia). Your veterinarian may try to get your cat to cough by pressing on its windpipe. If your cat is having extreme difficulty breathing, the veterinarian will give your cat oxygen to help it breathe before doing any more tests.
This is the most frequent email we get from exotic cat owners: “Hey, I’m really in over my head here! I got this thing as an infant. I bottle-raised it. Everything was great. But I can no longer handle this cat. I cannot housebreak it. It tries to attack people. I just don’t know what to do with it.'” This was an actual quote about a Serval, but we have had hundreds of similar letters about every kind of exotic cat.
Sorry to hear your kitty is scratching like that! Does he show any signs of skin infections, fleas, mites, wounds from other cats? The cone could have stressed him further, yes, if he was scratching already because of tension/anxiety. Open sores can get infected, especially when left untreated and scratched further. We would recommend taking your kitty to the vet for a diagnosis. They will be able to provide you the advice and medication your kitty might need. Best wishes!
