Cats are very dependent on their owners, and it is easy for cats to establish feelings with their owners. Their emotions are expressed by voice and body language. Cats have a unique personality. When I am with human beings, I am more of a friend and want to control her as a master. Kittens can recognize their owners according to the time you spend with them, such as feeding them and cleaning them. These interactions can bring kittens closer to you.
Cats can recognize people, just like the first time you gave this cat delicious food, maybe next time it will always follow you, because it already knows you and trusts you. From here, the cat should know people, otherwise, how could it approach you for the second time?
Extended information: cats often clean their hair. Kittens love to lick their bodies and clean themselves in many cases. After dinner, the cat will wipe its beard with its front paws and lick its fur with its tongue after being hugged. This is the instinct of cats to get rid of their own smells in order to avoid being tracked by predators. There are many rough protrusions on the cat's tongue, which is the most suitable tool to remove dirt.
If the cat is tired of being at people's feet and around, rub your head affectionately. If a cat rubs the smell of its mouth on you, it means it wants to take you for itself. If the cat purrs in its throat, it means that it is in a good mood. If the cat bends its front foot inward like a duck hatching eggs, it means that it is at ease and dependent. Cats show their trust by opening their mouths in front of humans.
