In a standing position, measure the height of your pet’s stomach from the floor. This height will be the height of the bottom of the hole in the wall. Make a mark on the wall at this height. If there is a large drop in the exterior wall of your house, you will need to provide a step in the exterior wall so that your pet can access the tunnel.
