I'm just going to say my

has a heated perch. There is a little plate that keeps him from getting at the cord and the cord is wrapped in a coil that's supposed to discourage chewing. The perch is cooler on one end and progressively gets warmer toward the other end.
The only time I see Skittles on it is when he is preening or napping. Other times he is more interested in his toys and food. I did take special care to move if as far from his water bowl as I could though. He does seem to love it though I do see why some people might be concerned about parrot safety. For me, the heated perch was just a better option than using a heating pad.
