This cat tower has a high profile that encourages cats to climb up and down with several jumping platforms. The upper platform is a perfect elevated place to overlook the entire house and the outdoor scenes. Your cats can safely hide in the spacious den and take a nap. Our cat tower is equipped with complete sisal trunks so that cats can sharpen their claws for hours. The stairs to the cave are also designed with a scratching board, which is inclined to train the back and shoulder muscles when sharpening claws. All the material is completely harmless to cats.
