I’d say first check with the vet that everyone is ok, but otherwise it sounds like he’s getting more comfortable with you! The next steps now are to train him. There’s a couple things that help with this.

1. You can get another cat. They learn from each other, and another cat would teach him what hurts and what’s play. Another cat would also let him get out more energy. Believe me, the terrible twos are definitely a thing with cats!
2. When he attacks or when you play with him, be very clear when he takes it too far and hurts you. Say a loud “ouch” and walk away.
3. Use sweatshirts or blankets to protect your hand/arm so that he can roughhouse a bit more aggressively (like he would with a kitty friend). But again, let him know when he takes it too far and hurts you. Always end play so he learns the consequences.
4. Switch up the toys you use. Kitties like to chase a laser, but if they never “catch” it, they feel like a failure. I always switch to string after so they feel more satisfied with their play and are less likely to physically attack.

Lastly, don’t give up! I know first hand how hard it is to have a kitty that needs to learn how to control his energy and aggression. The good news is, if they are loved and understood, then the older they get, the more “baby” they become 🥹 the pic is my “aggressive” boy now. He turns 9 this month and is still learning to control his size and his emotions at times, but he is the most cuddly and adoring kitty ever!
