Your cat will love the FurHaven Tiger Tough Skyscraper Playground cat tree! There is an adjustable spring at the top which braces it to your ceiling which makes this cat furniture secure and tip-free. The skyscraper playground also features an enclosed cat condo, cat shelves in different shapes and sizes, soft bowl hammock cat bed, sisal rope-covered scratching posts, springy-wand ball cat toys, hanging sisal rope and mouse toys! We recommend a maximum weight capacity of 18 lbs (8 kgs) for the Tiger Tough Cat trees. For cats at or near that threshold, there are some designs that may be a better fit because of platform size, post height and hangout/house size. One recommended design is the Platform House. We strongly recommend large cat and/or multi-cat households to place the unit near a wall for increased safety. For even greater security, webbing furniture straps may be purchased from your local home improvement center and used to secure the cat tree to the wall or other stable object.PRODUCT DETAILS: Gray; 26.8 in. x 17.3 in. x 100 in. to 113 in. AVAILABLE VARIANTS: The cat playground comes in Cream and Gray
