Ideal Pet Passage Screen Door

For entry through a screen door, Pet Passage is a simple solution. It is a quick and easy snap-in pet door that re-uses the screen you cut out for installation, thus allowing a perfect screen match. The sloping hinge side means that gravity will close the flap without magnets. As the pet door is supported by only screens on all 4 sides, Ideal Pet Products recommends that it be used for cats and less active and smaller dogs. Features include: Easy installation; locking door mounts into your existing screen door; and interior and exterior use. Flap Size: 9.75 x 10.5 inch.
