Abstract: A one or two story housing unit for a cat includes an enclosure having a roof portion, three solid walls and one port wall containing an opening through which a cat can enter the enclosure. Extending from the port wall is an open top porch area substantially surrounded by a vertical wall over which the cat can step and lie down in the porch or enter the enclosure. In the one story embodiment, the port wall opening is spaced from the bottom of the port wall and that portion of the port wall below the opening forms a portion of the porch enclosure. In the two story embodiment, a horizontal panel is positioned in the enclosure and the port wall extends from the horizontal panel upward to the roof.
