Cats are masters of landing on their feet, and for good reason—your pet has several physical attributes that give him great balance.

Why do cats have such good balance?

Cats are known for landing on their feet, but this level of feline finesse requires some complicated physics. Thanks to their keen flexibility and a specially designed inner ear, cats are masters of landing on their feet even from the most precarious of falls.

Cats have more vertebrae in their bodies than humans, allowing them to twist and turn with agility when they need to react quickly. This is especially important when your companion jumps or falls, as a cat uses his fast reflexes and flexibility to land on his feet. To do this, your pet uses his sense of sight and inner-ear balancing system to quickly determine which way is up, and then then rotates his front paws so they face downward. His lower body follows suit, allowing Kitty to quickly and seamlessly land on his feet.  In addition to their flexible spines, cats have other physical traits that help them land with grace, including their small bodies, light bones, and thick fur that serves to slow falls and soften impacts. Their collarbones afford them additional flexibility, too, as these bones are free-floating in felines, unlike other mammals. If you’ve ever noticed your pet fall back-first, you probably saw him twist his front end so his paws face the ground, with his hind legs following suit. His tail helps him realign during the fall, keeping Kitty level until he makes contact with the ground.

Even young kittens are adept at sticking their landings, as cats as young as seven weeks have developed an inner-ear apparatus known as the cochlea that provides a keen sense of balance. This fluid-filled feature combined with his sense of sight helps Kitty orient himself quickly when a righting reaction is needed at lightning speed. Even with their great sense of balance, however, it is important to keep cats living in upper-story apartments inside, as curious feline have been known fall out of windows attempting to chase birds or other animals. Though cats can often right their falls in less than a second, this does not mean they are immune to injuries from falling. Broken bones, missing teeth and trauma can result from a fall, sometimes with fatal results, so be sure to protect your pet by keeping windows closed. If you want to help him enjoy the outdoors safely from his home, you can invest in a perch or other accessory designed to give your pet unfettered views of his surroundings.
