It is often said that cats have nine lives. The reason for saying so is that cats have tenacious vitality, not that cats really have nine lives.
[sound wave healing]
When a cat is resting, it often makes a snoring sound in its throat. Some people think it's a cat snoring, but American scientists have found that this is one of the ways for cats to heal themselves. The reason why people call cats nine lives is closely related to the snoring of cats at rest. Scientists have pointed out that both domestic cats and wild cats will snore after injury. This snoring from the hair of the throat helps them heal bone and organ injuries. Scientists have also found from human experiments that exposing the human body to sound waves like the voice of a cat can help improve human bone.
Makin Sennar, director of the North Carolina Institute of faunal animal communication, said that because cats can heal with their own sound waves, the legend of the "nine life strange cat" is not absurd.
[not easy to be injured]
The cat's climbing ability is second to none among domestic animals. "Jumping up the house and over the ridge" is an easy task for cats. Sometimes they can even climb high trees. When being chased, the cat always quickly climbs to a high place and waits until its opponent leaves helplessly. The reason why a cat is good at climbing high and low is related to its whole body structure. We often see that cats fall from a high place without any damage to their bodies, while dogs fall from the same height, either death or injury. This is the origin of what people often say that "cats have nine lives". Why won't a cat get hurt after falling from a height? Scientists explained that cats have a well-developed balance system and a perfect body protection mechanism. First of all, this is related to the skeleton structure of cats. The spine of cats is particularly flexible, such as the sharp turn of cheetahs when hunting, and their movements are high-speed and flexible; Secondly, it is related to the ability of self posture adjustment when the cat falls from a high altitude, which is innate. This ability helps the cat reduce the acceleration caused by falling, and the tail also plays a very important role; Third, when landing, cats can usually ensure that their limbs touch the ground, and their foot joints effectively buffer the impact force generated at the moment of landing. In addition, the cat has developed limbs, short forelimbs and long hind legs, which is conducive to jumping. Its motor nerves are developed, its body is soft, its muscles and ligaments are strong, and its balance ability is perfect. Therefore, although there is a large drop when climbing and jumping, it will not fall to death due to losing its balance.
So it's hard for a cat to die in an accident, just like there are many lives.
