Duane and Betty Stewart of Busby, Alberta, have some of the most comfortable cats around.

Their solar cat shelter stays warm in winter, thanks to their "hot house" idea of incorporating a slanted glass face into the front of the shelter, which also features a "secret under-floor passageway" for getting in and out.

The animal enters through a hole covered by a rubber flap at the back of one side, walks diagonally across the ground level"basement," and enters the solar-heated area through a hole in the corner of the upper level floor. Inside, they are treated to a "pet bed" and a big dish of food. The "room with a view" protects them from wind, rain, snow, etc., and yet allows them to see what's going on in the yard.

The back side of the angled roof is shingled. The whole unit measures 28 by 24 in. deep by 37 in. high.

The hinged window panel lifts up for easy access.

During the summer the Stewarts just turn the shelter sideways to get the glass out of the direct sun, and prop a piece of wood under that panel to allow air circulation.
