Query: ...a Caveman can do it!

Great product!. This door is so much more than I expected. It has a little magnet in it to stop the door swinging after my cats go through, helping to keep air drafts at bay. I have LARGE cats and they fit through the door just fine. Also, I installed one in my garage door leading outside and works great; proving this door is not just for the interior of you home.
