How do they do it? Cats, even very young kittens, have an amazing sense of balance. When falling, the fluid in the inner ear shifts and the cat rotates its head until it equalizes and the fluid is level. The body automatically shifts to follow the head, and the cat lands on its feet.
It also helps that the cat is extremely agile and his supple muscles and spine respond instantly. A cat has 30 vertebrae - 5 more than humans, which accounts in part for this amazing agility.
However in a fall from 10 to 12 feet, there often simply isn't enough time for even an agile cat to complete the full switch to "feet-side down." Older, less-agile cats could be seriously injured, especially when landing on a hard surface.
