Hi, I am moving into a condo this weekend. It is two stories, and there is a railing at the top of the stairs where you can look down to the first floor. My kitty thinks he is super kitty and climbs on anything he can find. I am worried that he will try to climb on the railing and fall to the first floor. It is a long way down. Does anyone have any suggestions?? I know I could watch him like a hawk, but I want him to feel like he can walk around freely, and I don't want to shut him in a room when I am gone. I am scared to death that if he attempts to sit on the railing, he will fall and hurt himself badly, or worse, death.
