Your kitties will have lots of fun playing in and out of the many openings on this cube before taking a "catnap" on the sleeper tray on top, which is 13 1/2" square inside and 16 1/2" square outside. The sturdy design features a low center of gravity to prevent tipping and is 21" tall.  The inside shelf is carpeted as is the bottom and most of the interior sides. (13 1/2" square inside) Your cats will love this piece, starting as kittens until there adults, young and old alike!

All our products are made of solid wood and plywood - no particle board or cardboard is ever used. We use the highest quality carpets and sisal rope; and the undersides of all shelves and platforms are carpeted.
