Go to home depot or other big box hardware store and buy some minor gauge wire fence. You will need a simple pair of plyers and a really strong wire cutter and a strong staple gun. Cut the wire fence in to bits that you can hook together. Damm if I lived close I would come over and do it for free. You can craft a cage on your porch in any shape with these materials. You could easily combine it with the cat walk you have in place, pretty cool btw.
