CATDOLL : Why do cats rub their heads against people and make purring sounds?

When a cat rubs its head against its owner, it is showing affection. When a cat makes purring sounds in its throat, it means it is in a good mood.

Cats' body language also includes: when a cat is in a good mood, its eyes will be half-closed, its ears will be slightly tilted and relaxed, its tail will be gently wagging, its paws will be gently rubbed up and down, and it will not stare at anything in particular. Cats can also feel sad, but they will not cry like humans do, but will express it with their meows. Different cats have different meows, not just one. If a cat sheds tears, it is usually because of pain or eye disease.

When a cat is extremely frightened or angry, its tail will swing rapidly from side to side, its ears will lie flat, its tongue will arch, its pupils will dilate, its mouth will open with teeth exposed, its whiskers will curl forward, and it will hiss fiercely to intimidate its enemies. If a cat rolls or lies on the ground with its most vulnerable belly facing upward, it means that it trusts the people around it. However, you should not touch its belly casually.
