My bully was 4 years old when he started terrorizing my mom’s senior kitty. He didn’t start to calm down until he was 7.5 years old! Dante was the hyperest cat I have ever known; hence my saying I would have put him on prozac if I had to do it over again (& he was neutered at 4.5 months old.) Kicker toys didn’t stop his bully Iv or his pouncing my other cat and nipping him between the shoulder blades on days when he was really bored or on days when he was stuck inside. He treated my other (& older by a year) cat like a pounce toy when he was bored; his entire life. Catifying and reintroducing them might helped my 2 cats but it wouldn’t have helped stop Dante’s extreme bullying.
Luckily this case sounds way less extreme! Tire out your hyper cat’s mind, give him daily harness walks (or better yet a catio), build up your victim cats self confidence with daily 1 on 1 play (with your bully & possibly the other cat locked out), that plus catifying & possible reintroduction should put a stop to it.
My other cat quickly learned that I would not let Dante jump on him, if I was nearby. So he stuck close. They divided up the space and had what I thought was more of a frenemy thing going. Imagine my surprise when after Dante died, Salem grieved for him for over a year!!! So hopefully your senior and problem child will become frenemies or learn to ignore each other!
