Give your pet a nice, large bed to keep warm at night and/or during the cold months of the year, use the Petmate Heated Cat Bed. It offers a steady stream of heat on a round bed with walls that is made of suede and natural Berber. The smaller size and shape of the bed makes it ideal for cats, but will certainly work for tiny dogs as well. The soothing low voltage bed is designed to be used indoors exclusively, and simply plugs in to a standard outlet features a chew resistant power cord safe for your pets. The bed has a 15″ diameter and walls that are 5.5″ high.
