When someone asked me about my cat's purr, I tried to describe it. Many cats make different sounds when they purr, so you will have a very new description when you tell someone about your purring friend. I have had cats all my life and they all have had a unique purr.
Just like the purring, the meow from a cat is quite unique in many ways. One being is the meow can surprise you. Cats meow will get your attention so you will see what they actually want. It is a form of communication to you in cat language. Pay attention when your cat says meow.
You will sometimes look around the room trying to find out where that unusual sound is coming from in the close proximity. When you discover it is coming from your sleeping feline, it might surprise you. Cats do snore and they might make unusual sounds that you thought were something else. Listen closely and see if your cat snores.
It is not uncommon for even adult cats to make a sucking sound as they happily sleep. They are content and revert back to the days when they were at their mother's tit sucking to get their nourishment. It is not a danger sign, so don't think you have to take your sucking cat to the vet.
Some of the most alarming sounds a cat makes is the hissing. Take into consideration anything in the house that makes a similar hissing sound to be one your cat will not like. It means anger. When a human makes a hissing sound around the cat, you will probably see some signs of attention in your cat.
