This Tree Stump Kitty House is  not only very warm, cozy, and comfortable, it's a handcrafted work of art that takes a very long time to create.This house measures 24" in diameter by 25" high. The inside measures 13"x13"x 12" high. This house has a solid wood core with treated lumber for the base so it can sit right on the ground with no danger of rot or decay. The interior walls and floor are lined with carpet making it very cozy. The special phoam substance used on the exterior is an excellant insulator making the house extremely warm. The top of the house lifts of for easy access and cleaning and the knot- hole window is plex-glass. Each color of paint has 2 coats and then the entire house is sprayed with several coats of Marine Varnish Clearcoat for lasting protection. Please note that the door opening measures 6" in diameter and an extra large cat may not be able to squeeze through.This house does not have a door flap unless you order the door upgrade below.
