hello! My cat has been going to the vet constantly, for coughing, gaging, gulping, and loud breathing? noises. The vet examined him under anesthesia and said his throat was just red and irritated and sent him home with some antibiotics and prednisolone. He took it for a while but there were no changes. He mostly does the whole coughing gaging thing when he is exited. His vet can’t seem to figure out what is wrong with him, so i’ve been researching different sicknesses and seeing which ones matched his symptoms. I came across collapsed trachea. This is the only one i’ve seen that matched his symptoms and says it gets worse with excitement. What can be done to diagnose him with a collapsed trachea? I’ve seen that a fluoroscopy would be a good option but the animal hospitals around me don’t have the machinery to do that. There is a high tech specialist vet office about 2 hours from me, but it’s by referral only. Would i still be able to get a proper and correct diagnosis by getting a normal x-ray? is there any other options that could tell he has a collapsed trachea? he’s had chest x-rays before and nothing seemed abnormal, so that rules out some other sicknesses.
