Ok, I've bent the search engines so far, and still feel in the dark, so if by any chance, anyone out there knows anything at all, please, do tell! My already 8 years old cat has a thing: just before falling asleep or whenever he's receiving pets, he makes this popping like sound from his nose when he's blowing out the air. Sometimes he'll go a bit extra when the backrub is just right and go extra loud on those snorts like popping like snores sounds. He has no trouble breathing, he eats like a champ, the vet didn't do a detailed check on his respiratory system but otherwise deemed him health as he can be. Am I just being a paranoid "mom" and helicopter over the poor creature? Has anyone else noticed anything of the likes at any given chance? Am I slowly losing my mind? Thanks in advance, I suppose.
