Human heating pads are dangerous for use with animals. Even in uses with humans they can twist, over-heat and burn and short out. Many have mentioned looking for an alternative to the problems of heat lamps. This was my solution. http://www.revivalanimal.com/store/p/3024-Deluxe-Lectro-Kennel-Heat-Pad.aspx And to say I'm over-joyed would be an understatement. I get to choose the setting. It's water resistent, it's durable and designed for indoor or outdoor use. I don't worry about the danger of heat lamps. Heat starts at floor level and moves upward, so chicks still on the ground stay warm, and birds above still get any necessary heat. Or the choice of avoiding it. They have a cheaper fixed setting pad but I wanted to be able to set it lower as they all age. I don't use the cover that they sell for it but one I had from another dog bed, washable but doesn't get stuck all over with shavings. I'm totally happy. Thought I'd share.
