Abstract: A pet door assembly for insertion within a hole formed in a wall having a pair of exterior frames and an inner frame. The exterior frame members mount to opposite sides of the wall and define an opening for allowing passage of a pet. The central inner frame is located between the pair of exterior frames and define an opening generally aligned with the openings in the exterior frames. The inner frame includes mounting structure for mounting centrally a door in the inner frame and over the pet passageway. Appropriate assembly structure secures the exterior frames and the central frame together.
