Well, it's not exactly wheezing. Our 12 year old diabetic guy has been having this sort of "snuffly" sound in his nose and/ or throat. He's going to the vet later in the week but has anyone experienced this? It's not quite a cough and not a sneeze but he will make a sound that is raspy-er than a hairball. And then when you listen to him breathe it sounds like he has a bunch of mucus or something in his nose/ throat. To equate it to a human thing, when he's eating, it sounds like a person would if they had a completely stuffed up nose and had to breathe thru their mouths. So, it's a few different sounds. I think I've detected it before but it comes and goes. Last night it was something you couldnt' miss. He's an indoor cat. Thanks!
