The cat's tail not only makes it more gorgeous and charming, but also has the function of keeping the body balanced and completing some actions with the body. When a cat falls from a height, its tail will swing and its whole body will turn over in the air, so that its limbs will land first. The cat dragged its tail when it jumped up; When jumping down, the tail is raised; When turning sharply, the tail leans slightly to the turning side to keep the body balanced; When preparing to pounce on the prey, the tail is in a straight line with the body. As the body clings to the ground, only the tail tip swings slightly from side to side.
