There is only one reason why cats are angry with you, that is, they don't like you. It's telling you to go away and stay away from me. Don't force it to hug or slap it at this time. Cats are friendly to the people they like, such as coquetry in front of you, meowing at you and letting you lick them. Don't approach the cat when it is angry with itself, to avoid unnecessary harm to itself, and try to keep the cat quiet.
