My cat has been having audible breathing noises for a few months. No open mouth breathing, just audible through the nose, on and off throughout the day. She’s developed some weird other noises especially while sleeping or falling asleep some snoring, random sneezing as well. She isn’t overweight or old.
We’ve tried antibiotics but it didn’t help. The vets are quoting between $2-10k for just imaging for polyps, not even removal, if they see any. It’s impossible to afford it. She’s eating and playing and acting normal otherwise. I’m wondering what it can be, is it likely polyps and if I don’t go into debt to see, am I going to make her like unliveable?
I’m wondering if I can even rent a car and come down to a cheaper clinic in the US (I’m in Canada) which may be cheaper than doing it locally. There are very few low cost vets here and they only work with people on welfare so it wouldn’t apply. There’s a huge gap between people who are on assistance and people who aren’t but still can’t a afford $10k in imaging.

My 12 yr old Siberian Husky has always been a picky eater / grazer, but recently she has been acting like her mouth might hurt when she goes to eat her kibble. I took her to a vet near me and they want to do a dental with bloodwork and possible extractions, and quoted me almost $1300. Does this seem like a reasonable price? Are there any vets in Harford County, MD that might be cheaper?
