The view is always better from the top! Cats instinctively crave high spots, and the Penthaus bed is a comfy perch from which your pet can observe the world. The Penthaus fits snugly and securely atop any Standard Kitty Kasa using our Kitty Klip locking system. Use the Penthaus in combination with the Bedroom and Gym models to create a unique and appealing space for your household felines!
