Featuring a removable 20-Watt heater in the floor, this cat house seems to be the best choice for providing your cat maximum comfort during cold winter days. You can keep it in your garden with the heater active during winter, or you can remove it during warm days.
The heated outdoor cat house is covered in nylon and also features waterproof floor, soft foam lining, and waterproof vinyl. Your cat can enter the house from the back too as there are two doors. Find it at Hammacher Schlemmer, at $129.95.
