And again, I'd like to reiterate that I haven't just shown the success with my own collection. I talk to many high profile breeders who have been keeping snakes at a constant temperature for decades, and their snakes are in fact thriving. Of course a snake will use a heat gradient if it's available to them - however, I have seen nothing to convince me that they NEED this gradient to survive or even to be comfortable. It's like giving a boa constrictor a climbing branch - of course it will use it from time to time if it's there. But it certainly doesn't require it to live. Look at Tim Cranwill's example of the U of M - I don't think you need much more proof than that.
