All I know (for sake of arguement) is that snakes ACTIVELY CHOOSE different temperatures in the wild and in captivity ALL the time. Therefore, it would behoove us to allow them to do just that. If you don't, in my opinion, you are not giving that animal the best care possible. And I'd hate to think of people doing that.
I am out of it now too. But I just wanted to mention, before I leave, that THAT is exactly what I have been trying to say the whole time. Also, that breeding something or not have it die does not, in the least bit, attest to its health, well-being or anything else of the sort. My last analogy summed it all up I think, the bearded dragon one.
