Cat ran headfirst into window, not flap. Still, I like the product.

So, first off, let me say that I bought this "used, like new" and it was indeed like new. Not sure why anyone would want to spend the extra money for the new one. Next, it installs in a snap, it really does. And the foam insulation that comes with it is just the same standard foam that you can get in any home improvement store (or indeed, on Amazon). So if you want more insulation, it will cost you about three bucks! But I agree with the "Exit Only" reviewer, cats are not a quick study. I propped open the flap so cats could get used to this set up before the cold northeast winter sets in, but cat #1 sat outside the pane of solid glass to the right of the open flap, looking miserable, until she figured out that one inch to the left was the open door. But I guess she wasn't sure if it was a trap or something, so she walked to the other pane of glass all the way on the left and sat in front of that for a while, looking worried and forlorn. After a bit, she came back to the center, mustered up her courage, and jumped right through. Her success no doubt emboldened Cat #2 to give it a try, whereupon Cat #2 ran up and leapt head first into the pane of glass and not the open flap, then jumped down and scrambled onto the bed looking stunned. My teenage son ran up to her and asked her if she was okay. She looked embarrassed but did not seem seriously injured. I have now covered up the panes of glass with sticky notes to help the cats find the actual flap. YMMV.
