A walkway device is disclosed for permitting a pet ready access to both an inside and an outside of a home. The device includes a plurality of tubular members disposed on the outside of the home for the passage therethrough of the pet. Each member has a first and a second extremity, the members being interconnected such that the first extremity of each member is connected to a second extremity of an adjacent member so that the members define a circuit for confining the pet. The arrangement is such that the pet is permitted to move in a first direction through the circuit and to move in a second direction through the circuit, the second direction being opposite to the first direction. One of the plurality of members defines an opening disposed between the first and second extremity thereof and a pet door is sealingly connected to the opening. The arrangement is such that the pet is permitted to freely enter and leave the home through the pet door and to move through the members without any possibility of the pet escaping, becoming lost or being attacked while outside the home. The device also inhibits anything other than the pet from gaining access into the home through the pet door.
