Instructions
Measure the distance you want to run the tunnel. Divide the distance by eight and multiply by five to calculate how many sections of 1-inch-square 8-foot lumber you need.
For each 8-foot section of tunnel, cut eight 1-foot sections of wood from the 1-inch-square 8-foot lumber using the saw. Create a square with four 1-foot pieces of lumber by screwing through one side of one piece and into the end of the next piece. Make two of these squares per 8-foot section of tunnel, plus one extra for the end of the tunnel.
Stretch the chicken wire out along the path of the tunnel. If the chicken wire is too long, cut it to the desired length with the wire cutters.
Wrap the chicken wire around the square wooden frames you've built so that when you're done you have an open square tunnel supported by square wooden frames at either end. Secure the chicken wire to the wooden frames using zip ties. Use at least two zip ties per side. Place a wooden support frame every four feet along the length of the tunnel.
Close the chicken wire seam along the length of the tunnel with small zip ties every few inches.
Weave any loose wire ends of the chicken wire back onto itself to prevent injury to the cat.
