A cat’s tail and cry are both microphones to express its mood and emotions. When a cat is happy, it will raise its tail and bark at you. It may mean that it is happy to see you and hopes that you can come and play with it. Among them, the cat's tail is erect, its hips are arched, and its front paws are close to the ground. This is a sign that the cat is in a fighting state and is ready to attack.
