There is a big, BIG orange cat that likes to taunt my cats by hanging out by my bedroom window. This was bad enough, but now he's taken to jumping up ON the windowsill, and my cats go apeshit. I'm afraid they're going to hurt themselves trying to get at the guy outside. It happened twice yesterday, and I was there to break it up, but I'm afraid of what might happen if I'm not here to do so. I can't spray the cat without opening the window or going a fair distance away to the door and around to the outside. Does anyone have any suggestions as to what I might do to get this cat to stay away from my window?
