DIY Cat Window Box
Convert a window into a cat patio! Cut pieces of aluminum to the sizes needed for the legs and supports, and assemble the structure frame. Cut wood boards to the size needed for each shelf and one wall, cover the shelves with carpeting and wind sisal rope around the wall board until the board is covered. Install the shelves and scratch wall, attach pieces of wire mesh for the remaining wall areas and attach a piece of Plexiglass to the roof. Attach the structure to the window and place a wood board in front of the window with a cut out doorway to the window box.
