My one year old cat Maggie seems to breath really loud and heavy. When she lies next to me at night she sighs and almost kinda snores. She is a lil bit of a "chunk-a-monk-a" so maybe it's because she's a little overweight? She doesn't really sneeze very often so I am pretty sure it's not allergies. Last time I took her to the vet was last July when she was about 4 or 5 months old. Am I being paranoid or do you think I should have her checked out?
