Examples of cats recovering quickly after falling from tall buildings are found all over the world. A recent research report published in the Journal of the American Animal Medical Association pointed out that after investigating 132 cases of cats falling from an average of 6 stories, it was found that 90% survived. In another case, a cat fell from a 45-story building and survived.

Researchers in North Carolina are currently exploring the possibility of using sound waves to treat osteoporosis and stimulate bone regeneration in postmenopausal women. Poldi, director of the Department of Skeletal Metabolic Diseases at Hall University in northern England, said that human bones need stimulation, otherwise calcium will be lost and bones will become fragile. The purring of a cat's throat may be the cat's way of stimulating bone regeneration.

Poldi also said that it is very difficult to design exercises to prevent bone loss for the elderly with osteoporosis, but it is possible to treat bone injuries and help the elderly improve their bones by using the principle of cat snoring.
