Thank you for looking. This is for two pet doors, one size M and one size L. I purchased several items, but this one was unused, so I am listing it for sale. I opened it for the purpose of listing it. My cat has not used it. Returns are not accepted, so please check the photos and purchase only after you are satisfied. I purchased these on Yahoo Shopping, so you can find more details if you search for them. Please refrain from purchasing if you are concerned about minor details. They are in their boxes, so I will ship them as is with simple packaging. Thank you for your understanding.
