Pets of all sizes will enjoy the FurHaven Cat Tree Furniture Play Stairs with Cat-IQ Busy Box. This multi-level cat tree tower with interactive toys fills your cat and kitten's need to climb and explore. Natural sisal posts are the purr-fact scratching aids for your cat's claws. The top platform features a fun, spring-y ball wand toy and for an even better view, a perch at the very top is the best seat in the house (at just the right height for petting!). This cat tower also includes a fun and interactive Cat-IQ cat toy to keep your pet entertained and active. The cat tree furniture features two jingle balls for a fun game of cat-and-mouse (balls may be removed for play in or out of the unit).
