K&H Pet Products Outdoor Heated Extreme Weather Kitty Pad & Fleece Cover

This pad was great for our cat in his little box/shelf in his Catio (Cat patio). We mounted the cushioned warmer on his favorite sleeping shelf, & just prewarmed, as per directions, to make sure it was working correctly! As the fall temperatures got colder at night & he laid on it, he was at a very comfortably warm temperature when we put our hand on the bed where he was laying &/or used a thermometer to check on him! This pad is so intuitive, that it won't run warm if the weight of the cat isn't on it, for energy efficiency! Make sure that you clearly check the dimentions needed to fit onto the surface you'll lay it on. The Catio's bottom shelf "box" (our cat's favorite spot) to the left of the cage door was a bit too narrow, so my husband cut into the base of the box to slide the heating pad in from the side. We have that left side of the Catio covered in a clear plastic, so that the rain & wind didn't come into that side of the catio, which we kept on our back deck. The area you choose for the heating pad would need to be out of direct rain or snow. WE were VERY pleased to give our cat more comfort, while he had to be outside this fall, after he was old & started spraying all over the furniture. The Catio was put on a deck with no access to other animals-it was on an elevated deck.
