I have a neutered male indoor/outdoor cat (named Koopa) that has developed loud breathing within the last 2-3 days. He has always had a flat nose but never sounded like this. He seems to be normal otherwise...he's eating and drinking and doesn't seem to be overly tired just breathes loud and wheezy. This is a stray that I've tamed but I'm not sure if I can get him in a carrier to take him to the vet since he was neutered via a TNR program. I love him very much and have become VERY attached...any advice would help...thank you!
