Actually, from the science of it they would probably survive... Veterinary studies show that cats have a "dangerous range" of heights that falls within are the worst... Below the minimum they don't have time to position and land awkwardly with minor injury, but not fast enough to be severe, in the range they hit fast and still don't have time to prepare so cop the worst. Above the top of the range they hit their terminal velocity, which in their adopted falling position is lower than when not prepared, and land legs first absorbing shock. They suffer injury(pelvis and ribs most common) as they flatten out but survive with less damage than lower falls....even onto concrete.
So.... As weird as it seems a cat from altitude will probably walk away...
