In past, many scientists such as George Gabriel Stokes, James Clerk Maxwell, and Étienne-Jules Marey had shown great interest in the falling cat problem. It is a well-known fact that a cat which is falling upside down, has the ability to turn its body mid-air so that it lands on its feet. It's one more reason to keep our furry friends in peak condition.Vintage 1969 photos show how feline motion helped NASA solve its zero gravity problem. A healthy cat at its ideal weight can enjoy doing more acrobatic stunts than an unhealthy or overweight cat. They used these cats' responses to help astronauts orient themselves in weightless conditions. Researchers in that 1969 experiment discovered that cats in a gravity-free environment no longer had the ability to right themselves. What have humans learned from cats' amazing ability to survive falls?Įarly space explorers used cats in a study of weightlessness. It's always safest to keep your cat inside even during these balmy spring days. Many cats survive the fall but then get lost on the unfamiliar streets. Sadly, broken bones, crushed teeth, internal injuries, and worse can result. In fact, this behavior is so common, feline experts call it high rise syndrome. Some cats attempt to leap from crazy heights. A fall from several feet or even a few stories is not the same as a jump from the top of a Manhattan fire escape. Still, cats don't always land feet first. Only after righting its front half does the cat bring around its back legs to land first on its front paws and then on its hind paws while arching its back. This odd juxtaposition keeps the cat from spinning in the air the whole time they're falling. First, cats right their heads, then their front legs. It says the righting reflex we talked about earlier happens in a precise and predictable way. This National Geographic video helps explain why. Vesna Vulović, a human being, won recognition for surviving at 10,000 foot fall without a parachute, but most people wouldn't try it.ĭespite their aerial skill, many cats get injured in high falls, which is why we feline companions need to keep tight screens, closed windows, and sharp eyes. In fact, that cat walked away with a chipped tooth and a collapsed lung. Launching from an airplane in flight or the top of a New York skyscraper, for instance, won't have a happy ending.īut one lucky kitty did fall 32 stories and kept its life and wits. Their ability ability to relax while falling through the air at 60 mph is a big help.Ĭats don't generally survive falls from just any height, though. They know when they've reached terminal velocity, and they relax.
Cats in no gravity free#
It's the speed at which acceleration stops.Ĭats reach terminal velocity at 60 mph - or about five stories of free fall - whereas humans don't reach that same speed until 120 mph.Īlso, cats can sense when they're accelerating. Terminal velocity is defined as the speed at which a freely falling object (or cat) encounters as much wind resistance as it does gravitational pull. Why? The answer lies in terminal velocity. The BBC tells us that "In a 1987 study of 132 cats brought to a New York City emergency veterinary clinic after falls from high-rise buildings, 90% of treated cats survived and only 37% needed emergency treatment to keep them alive."Īccording to Knowledge of Living, humans that fall over 10 stories have a 5% chance of living to tell the story, but cats have a 95% chance of surviving the same fall. Yes! In fact, the higher the fall, the more likely a cat is to survive it. These things work together to minimize the impact of a fall. Plus, cats have no working clavicles, flexible backbones, powerful back legs, and low body weight. This reflex keeps them from grinding into the ground face first or back first. They can twist in midair so their feet are under them when they land. Nature prepared them to handle it.Ĭats possess a righting reflex. Like monkeys, snakes, squirrels, and other arboreal residents, cats take the occasional tumble from a limb. In the wild, cats are frequent tree dwellers.
Science offers an explanation for cats' amazing ability to survive falls.
Why can some cats survive high falls without hurting themselves? Do cats really have nine lives? Or does the answer lie in a combination of genetics, physics, evolutionary biology, and feline physiology? The cats themselves, however, never seem to think twice about taking a gravity-defying leap. Does your cat look like a daredevil acrobat when she's playing alone? It's common for cats to perform feats that dogs, birds, and other household pets could never hope to accomplish.
