I have four cats and one of them is terrified of everything such as a slight noise will make him jump. I have another who is very playful and recently started really picking on the scared one. I notice when my cat is about to attack him and I tried everything to get him to leave him alone.
My mom tries to hit him but I don't like that so I call him I try to get louder and louder to get him away but it doesn't work. It's like he's in a trance or something and he can hear me but he doesn't care.
I can't call him to give him treats because I do have other cats and they will smell it and then it becomes a feeding frenzy and then it feels like I'm rewarding him for about to pick on a cat. So I don't know what to do to get his attention so he can leave my fragile cat alone.
