warm and soothing
I have used one of these for years for any cat under the weather or kittens who are a bit sickly. I currently have a cat cage-confined due to an accident, the heated pad is put under her bedding and she curls up and sleeps on it. I think it helps ease the pain of her injuries and if it goes cold she complains until we heat it up again, which is not often as it keeps its heat extremely well. It loses a point only because it is a bit hard, a softer version might be more comfortable to lie on.
