The reason why the cat does this is to leave a signal on you, that is, it trusts you and likes your performance. In the future, it will distinguish you by the smell left on your body, so parents should not reject this behavior, but encourage it. This kind of behavior from your cat will take your relationship to the next level in the future.

Tip:

In addition to rubbing against you to express its trust in you, the cat will also express its trust in you in other ways, such as stepping on its breasts and exposing its belly in front of you. etc.
