I would be hard pressed to believe snakes kept at nightime lows that low would be feeding regularly and at all. Sure, they can survive those temps and I routinely keep mine between 55-60 degrees for three months out of the year. They are brumating and not expending energy or FEEDING!! Experience has shown me that they can and will regurge or not feed at all if the temps are not correct or optimum for them. Every snake is different with different metabolisms, just like humans, so there is room for error. However, I do not think a snake kept at 40-50 degrees everynight is going to feed well or at all regardless if the basking temps get up to 70-80 degrees in the day. In those situations, the snakes are probably not being subjected to the ambient temps due to burrowing below ground or within rock fissures, rotting wood, or under tin which all can keep the temps elevated to a more optimum temp.
