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: condo hideaways and scratching surfaces. Felines can sharpen their claws on the sisal scratching surface on the sides of the cubes instead of on your furniture or carpet. If a nap or a place to hide is in order, your cat can lounge in one of the beds on top or crawl inside one of the kitty condos, both are covered in plush fabric inside and out. Each condo has a cozy reversible cushion that can be handwashed. The larger lower-level condo offers two entry/exit openings and enough room for multiple cats to lounge together. Stack additional condo items (sold separately) to create a unique 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.
