Review on 🐱 CEESC Large Cat Door: 4 Way Locking, Weatherproof Cat Flap for Windows & Sliding Glass, Fits Cats & Small Dogs (Outer Size 11" x 9.8", Circumference by Jade Allen

Chinese standard design. The instructions are the worst instructions I have ever come across. They didn't even bother to paste their instructions via google translator to get some near understandable English. So if you can't "wipe" the installation of things, don't buy this. I bought this for our 2 inch hollow core bedroom door. In this room we only have one air conditioned window and we want the cats to be able to come in at will so it seemed reasonable to put in their favor. I expected there would be more work than they depict. Overall it took me about an hour or so. I measured and cut a hole, screwed the door on either side with some random screws I had, then built a frame to bridge the gap between the door pieces. Will not fit any standard American door unless you are trying to install it on a screen door for example. However, once installed it is of really decent quality. It's a nice soft plastic that cats won't hurt if they rub against it. on him. The door is a bit stiff, but you can get through with a little nudge. The lock works as it should. W We won't use a lock because we don't need it. To sum it up, Revain has better options. But if you're a bit savvy and have some time, it's not the worst thing you can get.
