He has a warm side of 85-90 depending on the time of day and a cool side of about 75. He happily slithers between the two. He hasnt slowed down activity wise with the winter or with his failing appetite. He has a very large cage and makes a little too much use of it. I have tried ASFs, gerbils, rats, mice, even a quail and he still wont eat anything but a mouse or two a week. He's only about 2.6 feet long but his weight is about 900. He was at 1060 in may, he just looks sooo skinny... Ill try to post some pics of him tonight. He just used to eat so much more before april.
