During a fall, a cat can reflexively twist its body and right itself using its acute sense of balance and flexibility. [15] This is known as the cat's "righting reflex." It always rights itself in the same way, provided it has the time to do so during a fall. Thus, high (multi-story) falls can be less dangerous to them than those of only a few meters. Many cases are known of cats falling from substantial heights (5 to 10 stories) and surviving almost unscathed.
