Custom made to order cedar house would be perfect for the neighborhood feral that is adamant about staying outdoors, or for the indoor kitty who insists on hanging out near you while you're in the garden. It is insulated with a Thermal-Ply insulation that not only keeps your pet warm in the winter, but also gives them a cool place to relax during the heat of the summer. The extra deck acts as a generous porch roof that helps shield the doorway opening from dripping rain and melting snow. The upper deck is great if your cat just needs to get away or just enjoy bathing in the sun. House Exterior: 19" x 18" x 18" (D x W x H).
