Pet Door Large Cats and Small Dogs - $15 (Goshen ny)

Cat Mate Pet Door.
Outdoor use.
Could be used inside also depending on the depth of the door.
Please close up on the pictures for dimensions so you will know if it fits your door.
BTW, I have the same one.
Working perfectly for 3+ years now on metal outside door right through ice, snow and heavy rain.
Does not freeze up and quiet little tap noise when it closes.
