Billy probably just LOVES it. (I call them HAPPY FEET when they "make bread") I do not keep electric blankets on the bed (14 cats is enough heat, thank you very much), but I use one when I sit in my chair in the living room and the cats really love the warmth. Cats that would not be caught dead sitting on your lap will all of a sudden say "OOOOO, let's go sit on mama!" The only thing I worry about is that they might chew the cord, so I do not let it unsupervised.
