Cat meets man Ziwei

Cats are domesticated by wild cats. Untrained cats often rub their paws with sand in the wild. This is the cat's genetic memory. Congenital memories will not be forgotten over time, so domestic cats have no sand to grind their claws at home, so they use cat claw boards to grind their claws. Some cats may scratch the sofa if they feel uncomfortable scratching the board. Sweat glands are hidden behind the cat's front feet, so it is of double significance for cats to sharpen their claws in places where they often haunt. Of course, cats also mark in other ways. When a male cat is in heat, he will find that he likes to pee everywhere. This is called spraying. There are sweat glands on both sides of the cat's ear bone, and you will find that Mimi likes to dawdle her master with her head. Cats also have oral glands hidden around their mouths, so sometimes cats rub against their belongings. Cats have tail glands at the root of their tails, so it is common for cats to wrap their legs around their tails at their feet.
