Why do cats need to use cats to scratch the board? What is the function of cat scratching the board?

Almost every cat family has a cat scratch board. Why do cats need to use cats to scratch board? What is the function of cat scratching the board? Cats need to use cat scratch boards to protect their nails so that they don’t get damaged on furniture at home. In addition, they can also use cat scratch boards to exercise to strengthen their muscle strength.

Anatomically, the nails on cat paws are a bit different from those on dog paws and human paws. Human and dog nails are largely degraded ancillary facilities. The most commonly used function of human nails now may be good-looking, such as doing a lot of manicures. Or pick your nose, ears, or something. The value of protecting the finger ends is no longer that great. Dog toenails also become less “important”. So, basically, the difference between humans and dogs in nails is not that big.

However, the cat seems reluctant. I don’t know what Mao Ye is thinking. He has become a master after spending so many years of eating and drinking. I still can't forget the days when I sleep in the open and unrestrained and loving freedom. They still like to chase, or they like to control "prey" with their paws instead of using their mouths like dogs.

So in terms of function, cat paws are much more flexible than dog paws. To ensure this flexibility, their "nails" grow directly from the last section of the phalanx and are unlikely to have obvious dimensional changes between the nails and bones of humans. In other words, the nails on cat's paws can be said to be "part of the bone". In other words, the toenails of cat paws are responsible for some functions and tasks of our human fingers.

Then, in order to ensure that the function and some abilities of one's claws do not deteriorate, cats must often use toenails. Otherwise, it may degenerate.
