This hook-on scratching post is great for varying their climbing environment. Sometime soon they will learn to jump from the ladder, or the stool if it gets moved poorly, into the fenced-off closet area. At that point the fence has to go. It’s not too bad, because they are clean and tidy kittens now. They also can climb to the top of the door barricade when it’s halfway up, but they haven’t yet jumped out in the hall. Once someone does, they’ll be flying out like popcorn, but bringing food will bring them back.
