Thank you for your reply. For the last few weeks we have had uncharacteristically cold weather. Nothing like what you've experienced, however. We've been at a balmy 18° for our daytime high off and on all last week. I just choose to do what I can to protect the health of my snakes while, at the same time, avoid paying a $400.00 a month gas bill keeping my entire house warm when I only use a quarter of it now that my children are all living on their own.
