The “Kitty Spa” is one of Lambkin’s and Boo’s favorite things. Although the it belongs to Boo, she lets her little sister, Lambkin, use it as well. There are ridges, bumps and all sorts of brush like and textures that feel good to a kitty. The middle has a little cup where catnip can go. As you can see, Lambkin has spread catnip everywhere and is relaxing very well. Some of the pieces come apart for easy cleaning and I have never had any problems with this kitty favorite.
