Why can cats shrink into small boxes like liquid?

Cats can shrink into small boxes like liquid mainly because they have many small bones, high flexibility, and excellent skin elasticity. Although cats have flexible bodies, their bones are also very fragile, so owners cannot force cats into narrow spaces, otherwise they may get injured. Additionally, it's essential to keep the windows at home closed. If a cat accidentally falls from a high place, even if its body is soft, it may still suffer fractures or internal injuries, causing irreparable consequences.

  1. Cats have many small bones

The physical structure of cats is different from that of other animals. They have 290 bones, and each bone is relatively small. Due to their unique body structure, cats can twist their bodies and squeeze into small boxes, looking like they're made of liquid.

  1. Cats have high flexibility

Almost all feline animals have highly flexible spines and limb joints, giving their bodies the appearance of being made of liquid. This is mainly due to the relatively large number of bones in their bodies. There are approximately 58 to 85 bones in a cat's spine and chest, which are very small and shaped like bows. These bones make the cat's shoulders look narrow, which is particularly beneficial for chest compression. Therefore, cats can achieve a body shape like a bow, seemingly able to contract freely.

  1. Cats have excellent skin elasticity

The skin elasticity of cats is also excellent, especially the skin between the abdomen and the hind legs, which is very loose. As a result, the range of motion of their limbs is very large, making it convenient for cats to shrink into small boxes like liquid.
