Cats generally identify themselves through smell, hearing and vision. Cats mainly rely on their sense of smell to identify themselves. When a cat-raising family starts raising cats, the cat will rub against you and sometimes point its butt towards you, and then come over to smell it. This is the only trace left by the cat on you. The smell it can distinguish is just like a male dog peeing everywhere, a cat can also distinguish familiar things by leaving smell.

Tip:

In addition to the sense of smell, cats can also distinguish familiar people through hearing. As long as you get familiar with the cat, the daily words you usually speak Cats can understand it. The most common thing is to call their names. I believe cats will respond when every parent calls their names.
