6. Purring
We all know cats meow but they make all sorts of noises, to ask for food, request a cuddle, tell you they are cold or want to go outside. They also make very specific noises when they are feeling happy and content, almost responding to your chat. The purring sound is a very good indicator that a cat is happy but a cat being vocal is generally a good sign. The more high-pitched the sounds are, the better, as sometimes the lower pitch meows can indicate they are frustrated and want something.
