Come and feel the softness and flexibility of the cat's body. It flows like a liquid, shrinks itself into a very small space, and tumbles 360° in the air. It can be described in four words: weak and boneless. And some people bend down and can't even touch their toes. Cats are ambush predators. Their success lies in their stealth, agility and speed. Cats are not like dogs that can chase their prey over long distances. Cats are sprinters. They lie in wait, wait for the right opportunity, and ambush with rapid bursts of speed. To make a cat such an excellent hunter, it requires the athletic agility to sprint, stretch, twist, squeeze into tight places, and run at high speeds. So why do cats do so much? So soft, how do you achieve such powerful explosive power? ​​​​​​

Let’s first take a look at the skeletal system of cats: The whole body of a cat is composed of approximately 230 bones. According to major parts, it can be divided into skull, spine, sternum, forelimbs, and hindlimbs. Judging from the picture, the cat’s skeleton is ordinary, but there are hidden mysteries everywhere!

① Spine: A cat has a total of 230 bones, of which 30 are vertebrae. A cat's spine can twist 180% in either direction! However, a human's spine can only rotate 90% in any direction! Moreover, adults have 33 vertebrae in early development, and the sacrum and coccyx fuse to become 24. , cats have 30 pieces (not including the coccyx or coccyx). Sandwiched between each vertebra is a tough pad of fibrocartilage called an intervertebral disc. Cats' vertebrae are more loosely connected than those of other animals, which increases their flexibility. Therefore, the cat's easy rotation in the air is due to its special bone structure: In addition, the cat's vertebrae are supported by muscles rather than ligaments, which increases the cat's ability to extend and contract, which helps the cat move at high speeds. Increase stride length when running. Long, flexible vertebrae and strong hind legs make cats excellent at running and jumping.

　② Shoulder blades: Unlike humans, cats’ scapulae are attached to the body through muscles instead of bones. The scapulae are only connected to the muscles on the sides, allowing the joints to move in all directions, so they have the ability to move at high speeds. Greater flexibility to move and stretch.

　③Clavicle: The cat’s clavicle is a tiny bone located deep in the chest muscle and is not attached to any other bones. This makes the cat's chest much narrower and deeper than other mammals, allowing the cat to squeeze into tight places. Cat’s unique muscle structure
