I rescued a male normal ball python about 5 months ago. He was kept I a 10 gallon tank with a screen lid and no heat, next to a bedroom window. He was kept very cold and fed very little. Only one large mouse once a month. Since I have gotten him he eats like a freight train and has his hides and heating fixed so he can be a normal snake. The weird thing is that he never goes to the hot side. He stays on the cool side. I tried lowering the temps and he still stays on the cool side. Even when I lower it to 78 degrees. Is it possible that being in the other cage made him like the cold?
