When cats feel relaxed and comfortable, they purr, a sound similar to snore. This sound usually indicates that the cat feels safe and comfortable with the people or environment around them. Cats like to rub their heads against people, which means they feel close to and trust you. This behavior can also help cats mark you as their territory. When cats feel content and safe, they will blink slowly. This usually indicates that they are satisfied with your companionship and affection.

Kittens knead their paws to increase milk production while nursing, and this kneading behavior is retained even after they stop nursing. When a kitten kneads its paws on soft objects (including your belly), it means it's in a good mood, so don't interrupt it.
An animal's belly is the most vulnerable part, completely exposed to the elements. If your master has opened their belly to you, it means they have given you complete trust.

While this is a sign of a cat's love, leaving dead mice, cockroaches, geckos, or even dead birds around you can be a bit unsettling. When a cat's tail curls up, it means they are enjoying their time with you and are happy and content.
This behavior is typical of cats that show mutual trust among themselves. Usually, they lick themselves, but if they lick you, it means they like you. Wherever you go, the cat follows. With every step you take, it rubs against your pants, covering them in fur. It won't stop until you understand its meaning and offer it food, at which point it will rush to the bowl and ignore you.
