How to reverse rough behavior
A few years back, we got my cat (who was only about 10 weeks at the time). Before getting him, I had done my research and knew not to rough house and use my hands to play with him because it might cause them to think that it's okay to be rough with people.
My brother, on the other hand, liked to rough house with him. I told him multiple times to stop it, but he obviously didn't listen.
Now my cat is 3 years old and a pretty large little man at 17 pounds and my brother is still seen as a toy. My cat will rub against him and try to sneak in a quick bite (which turns into my brother backing up and lifting his legs while my cat tries to get him), he'll stalk him going from room to room, and try to sneak attack my brother. I know this is not out of aggression but rather because of my brother's actions because my cat can be very sweet with him, such as grooming him and getting upset when my brother leaves without giving him some attention.
Is there any way to reverse my cat's behavior caused by my brother's stupidity?
Update: I probably should've specified he ONLY does this to my brother. When he wants to play with anyone else, he meows for attention and shows us the toy he wants to play with. Other than that, he wants to be snuggled and kissed by my parents and me. My brother will get occasional love but then he wants to rough house immediately after.
