The K&H Outdoor Thermo-Kitty Camper has it all! Utilizing our Outdoor Heated Kitty Pad as the source for warmth, this is the perfect heated shelter for any outdoor cat. Simply put it in a wood shed, garage, porch, barn or any outdoor structure and plug it in. We've cleverly incorporated 2 doors for that "just in case" quick exit from an un-welcome visitor. We'll admit, we thought of everything. UL listed.
