ABSTRACT:
A pet portal for use on a door, with an opening cut in it, permitting a pet, such as a cat or a dog, to enter a house without having to have anyone open the door for them. The pet portal includes a horizontal panel mounted on a slidably mounted vertical panel. The horizontal panel extends both inside and outside the door with an actuating means for pulling the horizontal panel and the vertical panel up to the top of the opening in the door so that the vertical panel covers the opening in the door. Both the vertical and horizontal panels slide downwardly against the actuating means when a pet steps on the horizontal panel either inside or outside of the door.
