Any suggestions for a heating set up for her outdoor enclosure for when temps dip this winter? The enclosure is roughly 4ft x3ft and the top is hinged to swing open. I was thinking of a Stanfield Piggy Heat Pad 2ftx3ft attached to the roof with a temperature controller to maintain a constant temp and it is supposedly water-resistant. I live pretty far south so there is no worry about extremely cold temperatures (freezes are pretty rare).
