Yes, loud enough to hear across the room sometimes. Once she was snoring under our bed, where it was getting amplified. I had to drag her out so she'd go snore somewhere else and we could get some sleep 😅
mine sometimes does a kind of "grunt". it's like snoring, but only one time and while he's fully awake. took him to a vet and they say it's nothing to be concerned about.
my fathers cat used to snore all the time while sleeping. but only once she was like 15 years old.
