Cats rubbing on you could mean four things:
One: Cats rubbing you with their bodies to express their love for you.
2. Smuggle: It's probably because cats want their owners to play with themselves, or because they want them to eat.
3. Interference: Cats mature in their six to seven months of age and then have an affair, and cats become very sticky when they have an affair, and they act like they do.
4. The smell: It may be to leave its own scent on the master, to make it easier to find you later or to swear its sovereignty. Last one. Next one.
