My son Eclipse is a 7 yr old Siemese who snores. At first ot was cute listening to his varying pitches of snoring. Well, its becoming an issue now with trying to sleep.
He is a very vocal cat, healthy, eats and potty's just fine. Is there something wrong with him? My other three don't snore.
It could be his nasal cavities are just formed differently, as usually it is flatter-faced breeds like Himalayans and Persians that tend to snore. Have his respiratory system checked next time he's at the vet, but otherwise, ear plugs may be in order!
I have an oriental short hair (which is similar to a Siamese) and when he's in really deep sleep, he tends to snore too. I think they are just really, really comfy! LOL If you're worried, it wouldn't hurt to have him checked out like Karen mentioned. Enjoy your loud baby!
