Designed for cats who love to climb, lounge, and be one with the outside world. What cats don't? It's part of who they are. Combines your cat's natural climbing and scratching instincts with the environmental enrichment they need. A better alternative to the potentially dangerous free-hanging window perches and hammocks that limit your cat's activity and natural scratching instincts. Easy assembly, 10-15 minutes total estimated time. Includes three heavy-duty suction cups that can easily be attached to any supporting window in your house and a free-standing base for added support and peace of mind. The Set Includes premium EO grade MDF, Sisal Posts, Suction Cups, Sleeping Pad, and organic USA-grown catnip leaf to entice your cats.
