Cat Mate Large 4-Way Cat Door for Large Cats and Small Dogs with Magnetic Catch and Durable, Rigid Flap - Brown

I shopped around and read reviews for a long time trying to decide on a cat door and picked this one because it's brown and seemed big enough for my large (18ish pounds) cat. It has worked out perfectly. I installed it on the interior door that leads into my garage and I love being able to get the litterboxes out of the house. Both cats took to it very quickly; I did leave it taped open for a couple days first, then when I un-taped it that understood what the deal was.

This was easy to install and my large, fat cat approximately 28 pounds can use it as well as my other normal sized cats. Keeps the dogs out of their food and litter boxes

it swings in only, out only, both ways or locked, just like its suppose too. the doors swings nicely and it closes tight. the install was easy for me, I custom built a wall for it. If you're going to install it in a door using the instructions, I have no idea how easy or hard it would be.

Pretty good door. The is a lack of instructions for installing it but installation is pretty intuitive. The screws were too short for my door and I had to buy longer ones. The locks were a little stiff and had to be worked in.

Cats learned and love the easy access tj out basement. Keeps us separate but together
