This heated pad has been installed in a outdoor "Cat House" (Feel free to snicker) Mr. Keekers was slow to make use of it . Then one 20 degree morning and the pad has become the favorite bed . Keeks is eight pounds and curls up nicely on the small size. This product is easy to clean and has a washable/removeable cover. Ajustable firmness. The cat appears far to cozy! I like that it is rated for outdoor use. Not much to look at out of the box. However I would gladly recomend this to all cat owners. I will use K&H Products in the future. Have also noted the 16 year old cat has freer movement in the mornings.
