We had our 2 yr old cat neutered when he was 6 months old. At that time, he got extremely ill due to fluid entering his lung during surgery. Since then we have been through a few bouts of him getting what sounds like a deep lung congested cough and he is put on antibiotics. About 2 months ago, we took in a few stray kittens and they were infected with upper respiratory infection, which set off our adult cat once again. He has now been coughing for about 4 weeks. We just received our 3rd round of antibiotics yesterday and this time it will be administered with another antibiotic that is suppose to work in conjunction with the original antibiotic. I love our vet, but I am not convinced that the vet is doing all that needs to be done. Personally, I think the vet is covering for what happened during his surgery 2 yrs ago and will not admit that this will be an on-going issue for him. Could the fluid in his lung during surgery effect him for the rest of his life? And should I be seeking care from another vet or is antibiotics my only solution? I donâ€[emoji]8482[/emoji]t know what to do next....
