Review on PAWSM Interior Cat Door: Concealed Litter Tray & Brush, Easy Install, Fits up to 20lbs, No Training Required! by Robert Trevino

Very easy to install. I finally have a laundry/utility room large enough to fit my crate and food in it, so I needed a door. I bought the larger one first but of course when it arrived I found that I couldn't use it with my type of paneled doors. So I opted for this one instead. . I don't have a workbench so I put it on four chairs in the dining room (see picture). The bottom of the door was harder to get through, so I placed it against the door to press firmly with a jigsaw. My jigsaw made marks on the edges of the door but luckily I had the inside of the door up so it was hidden. Having just installed it, I'm not sure how well the adhesive strips will work, but I hope they last. Overall I'm very happy with it.
