A pet door assembly is disclosed that includes a support structure that defines an access opening through which a pet can pass. A connecting arrangement is positioned on the support structure to permit the support structure to be connected to at least one connector able to be fastened to an inwardly facing surface of a closure frame. A self-closing door is mounted on the support structure to be displaceable between a closed position in which the door closes the access opening and an open position. |
