The barrel-shaped cat house is designed with a scratching board, which can help cats sharpen their claws while preventing cats from damaging your furniture. Besides, they are crafted with natural sisal, ensuring safety. Thanks to the removable condo outside cover, the cat house serves different purposes. With the outside cover, it provides private and warm resting areas for kittens. And without the outside cover, the cat tower promotes air circulation while making it easy to clean the interior space.
