DIY Wall Cat Run
Build a cat run that attaches to the side of your house! Select an area next to a window that your cat would enjoy. Cut pieces of wood for the frame and assemble the structure. Cut pieces of wire mesh to cover each open area of the run and cut pieces of plywood to fit across the bottom. Attach the wire screens and plywood to the frame. Install a cat door in the window and attach shelves to the wall for your cat to use as a perch. Drill the structure onto the wall and modify the area to meet any needs for your specific location, such as a covered area for shade.
