I have cats who slept silently, wheezed and snored...no worries.
As with anything, keep an eye on kitty. Look for changes in behavior, appetite, box habits...no change, all good. changes...consult the vet.
Take care - Pip
I Have 8 cats, and they ALL snore!!!! Hahaha.
I have never been worried about it, To be honest I thought it was Normal, cause Dog's snore.
You can get him checked if it puts your mind at rest.:)
