Only slightly.
OUR barn cat resides (when he feels like it) in the old plastic doghouse the 4 goats used to get in when they were young. (I doubt that little Gracie could fit in it now)
It has a raised floor of a chuck of sheetmetal roofing nailed to a couple of 2*4's with a lightbulb underneath.
Radiant heated flooring: PBBBT!
It sits on the deck right outside the kitchen window so he can call for supper easily.
Oh; did I mention he has wall-to-wall carpet in it?
Turned the heater off in my outdoor pipe closet yesterday. This morning they were frozen when I came out to the coffee shack. Should get me some of that radiant heat. Took about fifteen minutes to get the water running again, but alas we are all warmed up now having that first cuppa.....
