Snoring: Should I be worried

I have 4 cats. 2 Males and 2 females. Magick (M) and Monkey (F) are both snore when they sleep. I know they say snoring in people, at least, can be a symptom of a bigger problem and can severly effect your health but what about cats? I have been kicking my self because we just had Magick at the vet and I forgot to bring it up. Monkey, Falla or Onyx need to go next so I do plan to talk to about it then but is it serious enough to set up an appointment just for that? Any imput would be greatful.

One of my girls, Betsy Sue snores. Our vet says it's fine, but of course check with your vet too.

My Josie snores so loud that she wakes me up. Our vet said she had a deviated septum and not to worry about it. We always know where she is sleeping.

Monkey also feraks me out because she sleep so deeply. My husband will pick her up and he can carry her all the way to the bedroom before she even starts to wake up. My other cats don't sleep deeply at all. If you look at them funny they wake up.
