Cats are one of the animals very skilled at climbing and ascending. At home, you can often see cats jumping from cabinets onto doors, or climbing step by step to the top of a cat tree. Cats also like to climb railings; sometimes when you come home, you might see a cat leisurely hanging on the balcony railing. Do you know why cats like to climb railings?

　　Another reason cats like to climb railings is because their bodies are built for climbing. Cats have very sharp, curved claws, which help them grasp and cling to objects. Additionally, the muscles in their hind limbs around the joints have strong contraction ability, generating powerful thrust that gives them excellent climbing skills. Moreover, cats have flexible spines with strong bending and stretching ability, so they move quickly and agilely while climbing upward.

　　Strictly speaking, cats liking to climb railings is also influenced by their living environment. Before cats became pets, they faced dangers in the wild; to better avoid enemies, they gradually developed climbing abilities. When cats hide in high places, they can avoid attacks from predators more effectively. Climbing is actually an instinctive form of self-protection in their life activities. Of course, this climbing-loving gene continues to this day in cats.
