Abstract
A pet door includes a motor for locking and unlocking a pet flap of a pet door. The pet flap is rotatably attached to an upper portion of the pet door. The flap has at least one peripheral edge and a movable seal coupled to the flap for reciprocal movement between a retracted position and an extended position. The seal has a second magnetic portion that is magnetically attracted to the first magnetic portion of the frame.
