L9(2)：Flying cats
All these cats hadone experience in common: they had fallen off high buildings, yet only eight ofthem died from shock or injuries.
Of course, New
York is the ideal place for such an interesting study，because there is no shortage of tallbuildings.
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 likewell-trained paratroopers.' a doctor said.
It seems that the further cats fall, the lessthey are likely to injure themselves. In a long drop, they reach speeds of 60miles an hour and more. At high speeds, falling cats have time to relax. Theystretch out their legs like flying squirrels. This increases theirair-resistance and reduces the shock of impact when they hit the ground.
