ABSTRACT:
A two-way animal door and frame having an outside frame and an inside frame is adapted to fit over a cut out opening in a door or a wall for allowing passage of a pet through a pliant door and border so that the pliant door and border will seal off the opening when not in use to prevent cold air and the like from entering the house. The upper ends of the pliant door and pliant U-shaped border are attached to one of the frames by a peg-and-hole securement. The two frames fit flush to their respective side of the door or wall and are secured to each other by nuts and bolts to keep both frames in place and for pushing the edges of both frames and the pliant door and border flush against the door or wall.
