What do cat's expression and action language mean respectively?

The so-called "cat's expression and action language" means that cats express their feelings and desires with their ears, tail, hair, mouth and body.

1, ears flat, body arched, tail straight, hair standing up all over the body to show vigilance or anger.

2. Sit still and wag your tail to show happiness.

3, it will keep grinding it around your feet, greeting and coquetry.

When the cat is lying or sitting, its pupils contract into a straight line, and its eyes are half-open or even completely closed. It will wash its face and ears easily with its forefoot. Lie down, stretch forward, or curl up. When it is full of drowsiness, stretching its front legs low before and high after the meeting indicates calm.

When you go home, it will run to the door and sit down, wagging its tail slowly and vigorously to welcome you.

6. When it purrs, it means that it is in a good mood and happy. Sometimes you stretch your legs, and when you are particularly lazy, you will also purr. In addition, when it is sick or in pain, it will also purr.
