We, who have lived with cats for a long time know that cats snore. Some cat lovers and owners comment on the fact that cats snore:
"Yes, my cat was a silent sleeper until she was a 7 year old, when he began to gently snore much to my amusement. The vet said all was normal. Quite funny".
"One of my cats (I have three), a ten year old orange boy tabby (he is huge at 20+ pounds) snores so loudly that sometimes I have to wake him up, gently, to stop him. He starts up about 10 minutes later but I normally get off to sleep myself in the meantime!"
"I've got a massive cat at 20 lbs and he snores sometimes. His whiskers twitch like mad and his legs jerk around aswell. I am sure he is chasing a mouse as he has brought them in (when he is awake!). He is big enough to reach up to the kitchen counter. He's a bit lazy so he prefers to reach up rather than jump!"
"I think that cats snore because there is something wrong or different with their nasal passages. It's normal and cute....."
