The inner scratcher can be removed and replaced. The front and back sides of the cat scratch board can be used, and its service life is twice that of other ordinary cat scratch boards. Every cat should have a bowl-shaped cat bed that cats love. It is not only a scratcher but has a certain curvature and cats love to curl back up in it which is one of the cats' favorite postures. Strong enough to hold weight up to 25lb. It is a good size for a cat to sleep in it, wake up, stretch, get her deep scratch in & curl back up in it. The base is made of high-quality environmentally friendly plastic, waterproof, strong, no need to replace, and can be used for a long time. Just open the box and it's ready to go! It's white so it blends in with any decor and doesn't stand out like all the other toys.
