This mat is fantastic to use by itself or like I have, as an overlay on a large heating pad. I have a giant heating pad for my kitties so it doesn’t fit in the pocket in the mat, but look at the picture of my Pretty Patty enjoying a nice warm sleep (mat on top, heating pad on the bottom). I bought two of these so I can switch them when I wash one. These mats would be great in a carrying crate too, but you would probably have to fold it. Very comfy
