Cats
The way cats make friends is by leaving scent. When two cats meet, if they feel good, they will rub each other and let each other leave their scent, so that the next time they meet, they will not be strangers.
1. Sweat glands are distributed in many parts of cats’ bodies
When cats come over to act coquettishly towards you, they will rub all parts of their bodies against you. Not to mention the face and body, even the tail will wrap around your feet. Cats don’t just do this to people, they will also rub their bodies against furniture or small objects. They do this to leave their scent on their owners or things in their homes.
Many parts of a cat’s body have glands that secrete scent, such as the sides of the forehead, the sides of the lips, the lower part of the jaw, as well as the tail, flesh pads, etc. The glands on a cat's head and tail are used to rub their scent onto objects, while the glands in their pads are used to leave their scent wherever they pass. In addition, cats also have secretory glands called anal glands on the left and right sides of the anus. Their main function is to dye their excrement with smell. However, cats sometimes use their anal glands to rub their buttocks against objects to leave behind scent.
2. The way cats express love
The juice glands throughout the cat’s body secrete a smelly substance. Cats often rub this substance onto items close to them to declare ownership of the item. It can be said that the cat’s behavior is marking its territory.
When it comes to marking, it is well known that dogs mark by peeing. In fact, cats in estrus will also use urine to mark. In addition, the behavior of cats sharpening their claws is to repair nails on the one hand, and on the other hand it is also marking.
The reason why they rub against their owners and make marks on them is probably because they regard them as "their own things"!
Cats leave their scent on their territory so they feel very reassured when they smell it. The reason why cats leave their scent on their owners is because they regard their owners as partners who can reassure them. So don’t say no to cats that rub against you. Not only that, you can pet them and leave your own scent on them.
