Abstract
In general, existing pet doors are unnecessarily complicated and consequently expensive to produce and/or install. The pet door of the present invention overcomes these problems and provides a readily visible indication of whether a pet is inside or outside a house. The pet door disclosed herein includes a pair of simple rectangular frames carrying a flexible flap with a weighted bottom end for overhanging inner and outer ledges on the bottom ends of the frames, inside or outside of the frames depending upon the location of the pet, i.e. a pet moving through the door will push the flap through the frames, the weight returning the flap to a closed position in the frames with the weight against one bottom ledge.
