Our new puppy loves this bed for his crate. It is thicker than many of the other crate mats we have looked at and extremely soft. I also appreciate the little silicone pattern on the bottom that keeps it from moving around since we take it in the car. I can’t speak to the self warming piece though. We have a self warming bed for our cat and it has reflective fabric on it similar to what you find in a Columbia omniheat coat. This has nothing like that. Either way it is our puppies favorite mat and so far one of the few he hasn’t chewed to bits. That alone makes it 5 stars for me.

So I have several self warming pads, this is the first one all three cats like. The outer cover is similar to the fake rabbit fur blankets and that was a huge hit in my house, everyone kneaded it excessively. While the pad isn't thick it does generate some heat keeping my smallest cat warm. And even my fattest guy liked it. It is made well and I am already ordering a second.

Small cat (or dog) warming bed.

Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey

LOVE this warming cat bed!! With a tiled or cement floor, this is an ideal strategy to remind little pets that this is a warm spot for you to lay your head <3

Great.

Size: 27.6"L x 18.8"W x 0.5"Th, Color: Grey

My cats love these. Will choose these over and over again. I had to buy multiple so they could each have one. Does seem to help keep warmth in. It’s also easy to clean.
