A pet portal flap assembly has interior and exterior frames between which moveable flaps are mounted in a swinging door, or in a patio door insert, or in an exterior wall, to permit both ingress and egress of a pet. A handle operated mechanism is provided for selectively vertically positioning the moveable flaps in an uppermost position to permit both ingress and egress of a pet, in a mid-position for only permitting ingress of a pet, and in a lowermost position in which bottom portions of the flaps are locked between the interior and exterior frames to prevent any movement of the flaps.
