An animal structure fit for varying climates. The structure may have sub-assemblies that are assembled in a manufacturing facility, and then shipped as a group of sub-assemblies to an end customer. The animal structure may include a floor raised from the ground, insulation in walls, and insulated floor and top cover. A standard sized opening for animals to enter and exit may be placed in one of the walls. The top cover may be hinged for access to an interior of the animal structure, and the floor may be removable for ease of cleaning.
