The TRIXIE Crazy Cube Stackable Cat Condo provides endless opportunities for your cats to play, scratch, explore, or relax. This stylish piece of cat furniture combines the best of both worlds: a condo hideaway and a scratching surface. Felines can sharpen their claws on the sisal scratching surface on the side of the cube instead of on your furniture or carpet. If a nap or a place to hide is in order, your cat can lounge on top of the plush-covered condo or crawl inside the luxuriantly soft-covered kitty condo and rest on the cozy reversible plush cushion. Stack additional condo items (sold separately) to create a unique cat fortress and collapse them when they are not in use to save space. This is the perfect retreat for cats of all ages; cubes can hold up to 35 lbs.
