Your cat will enjoy a birds-eye view of the outside world perched upon his Orthopedic Kitty Sill. Surely a favorite for the curious cat, this perch doubles as a sturdy sleeper with its comfy faux lambswool cushion and can be purchased with a heating element to keep your pet toasty warm. The sill's attractive oval and scroll design is constructed of advanced engineering for strength and ease of assembly. Its dual thermostat heating unit is buried deep within super soft orthopedic foam and is removable for year-round comfort. The heater is pre-set to keep the sleeping surface 12° to 15° above ambient air temperature and warms quickly to your kitty's natural body temperature. This may just be the perfect seat in town!
