I have a senior cat who goes into labored open mouth breathing when he is in a hard purr and also has wheezing and snoring but otherwise acts normal – eats, drinks, and is active for his age. The snoring is even when he’s not in a deep slumber and it can be an airy rattle if that makes sense and he has a little squeak when he swallows. I saw your video on the cat with a polyp and thought maybe this could be what he has except that he’s almost 17 so the vet suggested it probably isn’t since that’s more of a young cat thing but did suggest a scope and CT which will cost me 2500-3500 and he will have to be put under. In reading about breathing, heart disease can also cause breathing problems and since he has heart disease I would hate to spend all the money and put him through that to be told the scope didn’t show anything. I’ve also been reading about asthma, but my regular vet nor the specialist even mentioned that it could be that and from what I’ve read, it’s hard to diagnose. He’s a flame point Siamese and he has early ckd and some heart disease (stage 3/4 systolic murmur and hypertension), so I’m nervous about putting him under. Aside from these “old man” things, the specialist and my regular vet say his labs are spectacular. The specialist said when she is presented with a cat that has these conditions, they bloodwork and labs never look this good. So I certainly don’t want to put him down if he looks good but I also feel like he can’t be comfortable with these breathing episodes. One thing to note, when they did bloodwork a couple of weeks ago, his eosinophils were elevated which I have read can be linked to upper respiratory and asthma. Im putting the link to videos of the wheezing and purring to see if you’ve ever seen such a thing in a cat. I sure wish I had you closer by. Thank you so much!
