Built for feral and backyard cats that need a dry, warm spot no matter the season, this 24 x 20 x 21 inch shelter is framed in cedar with six-sided foam insulation between the panels for real cold and heat protection, not just a plain wood box. A sloped, waterproof asphalt roof with eaves over the door keeps rain off, and raised waterproof feet stop moisture from creeping up from the ground. The door has a thickened, removable PVC flap you can pull off in summer for airflow or leave on in winter for wind and water protection. Cleaning is simple since the roof lifts open and the bottom panel comes out, and an internal partition keeps eating and sleeping areas separate. At 20.5 pounds and finished with pre-drilled holes, it goes together with basic woodworking screws and no special tools. It comfortably houses 1 to 2 cats and works well for rabbits and guinea pigs, indoors or out.
