My Meeko is now 9 months old and he has taken to bullying my mom's cat who is older, smaller and more timid. He doesn't seem to want to hurt her -- I think he wants to play -- but Kitty LuLu is terrified of him and hisses, cowers and runs from him. They each have their own boxes, feeding stations and rooms, but whenever she appears, he pounces on her. When we shut her up in her room, Meeko meows and makes the strangest "mating call" noises because he wants her. They are both fixed, however. When he is after her, he cannot be deterred unless she is picked up and removed from the situation or there is absolute interference with his aggressive behavior. How do I stop him from being such a bully? By the way, the dog LOVES playing with him (miniature Aussie). They wrestle and jump on each other and have a great time! If only Meeko would learn to leave LuLu alone. :-(
