OUR LARGE HOUSES HAVE A FLAT TOP SO THEY WON'T BE TOO LARGE TO SHIP UPS GROUND. The house measures 21"x21"x23"h on the outside and 16"x17"x14"h on the inside. The base is treated plywood that will not rot or decay. The floor is vinyl with removable carpet on top. The walls and ceiling are also lined with carpet. The floor, walls. and attic are all insulated. The house is heated by a 50 watt infrared bulb that screws into a recessed light fixture in the ceiling. There is an adjustable thermostat right inside the door where you can adjust the temp. The bulb only comes on when heat is needed. The front of the house opens for easy access and cleaning. This house has the large commercial door upgrade for that fat cat. There is also a paw-print window made of plexi-glass. House has a 20 ft cord. The siding and trim are left natural and finished with a clear penetrating sealer.
Do not wait for cold weather to order your Cat House, Cats need plenty of time to get use to the idea of using a new house.
