  • We all know cats always land on their feet. But how far can a cat fall and still survive?

  • Humans that fall over 10 stories only have a 5% chance of survival. Cats falling from

  • the same height have a 5% chance of dying. This doesn't mean to throw your cat off a

  • building to test this. Biologists have already done that. In a 1987 study of 132 cats that

  • fell "accidentally" out of skyscrapers, 90% of them survived. One cat fell 32 stories

  • onto a concrete sidewalk and suffered only a chipped tooth and a collapsed lung. What

  • is even more interesting is the fact that the farther the cat falls, the higher its

  • chance of surviving is. At first this is slightly counterintuitive. The farther you fall, the

  • move you will accelerate, and the harder you will hit the ground.

  • so how can a cat falling from 10 stories have a high chance of surviving than a cat falling from 3 stories?

  • Well the answer to that question is:

  • Terminal velocity.

  • Terminal velocity occurs when the resistance force of the air you are falling though equals

  • the downward force of gravity. You stop accelerating once you reach this velocity. Unfortunately

  • for humans, this velocity is around 120mph. Surviving a crash at this speed is quite unlikely.

  • However the terminal velocity of cats is only half of that at 60 mph. But that doesn't explain

  • how cats have a higher chance of surviving at 10 stories versus 3 stories. Well, that's

  • because cats can sense acceleration;

  • when a cat is falling and accelerating downward, it can sense that. It has a sense that

  • is able to detect whether it is accelerating or not

  • when the cat is not accelerating anymore, AKA reaches terminal velocity

  • it relaxes it's body more and the impact is not a rigid

  • Let's walk through a hypothetical situation of a cat falling

  • from a skyscraper. The cat jumps off and rotates herself around so her feet are underneath

  • her. At this point the cat is kind of freaking out because she knows she is accelerating

  • downward. Her limbs are tight and if she were to hit the ground now, she would suffer more

  • injuries due to her stiffened body. But as she falls farther, she reaches terminal velocity

  • impact. She walks away with minimal injuries and hits the catnip.
