L9(2)：Flying cats
All these cats had one experience in common: they had fallen off high buildings, yet only eight of them died from shock or injuries.
Of course, New York is the ideal place for such an interesting study，because there is no shortage of tall buildings.
There are plenty of high-rise windowsills to fall from！
One cat, Sabrina, fell 32 storeys, yet only suffered from a broken tooth.
'Cats behave like well-trained paratroopers.' a doctor said.
It seems that the further cats fall, the less they are likely to injure themselves. In a long drop, they reach speeds of 60 miles an hour and more. At high speeds, falling cats have time to relax. They stretch out their legs like flying squirrels. This increases their air-resistance and reduces the shock of impact when they hit the ground.
