I wish he’d leave too, but if I go after him too hard, then it scares the kittens. They think I’m after everyone. So I just shoo him the best I can and try to make sure there is very little for him to eat when they’re finished. Just a few crumbs. I don’t need a bully around.
You need to find a really good water pistol so you can squirt him when he shows up. A lot quieter and gets the point across.
