This is possibly the best thing I have ever bought for my cat. I put it under a couple baby blankets because it is a hard disc but it stays warm for at least 8 hours and while it's warm my cat wants no part of getting out of her bed. I'm so happy because before she would sit on the cable box, heat vents etc. and I was always worried she would get too hot so this is AWESOME!!!!!
