CEESC Extra Large Cat Door (Outer Size 11"x9.8"), Weatherproof, White, ABS Material, 4-Way Locking Flap for Cats & Dogs up to 25.54 lbs

Easy to install. Large enough door for my big fat cat. Easy open flap for even my smallest cat. Door has locks so you have total control of entry and exit. You are able to choose no entry/exit. OR, you can choose unlocked for entry locked exit. Or exit only with no entry. It’s perfect! I did install the door in a window. I couldn’t find an affordable window option in this price range that would accommodate my biggest cat. I made frame from plywood to suit my need. I added some “stained glass” vinyl for a little more privacy. Because it is in a bedroom window. I’m very happy with the door. I would recommend because it is easy to install. It is sturdy. It has a framed in look when installed.

Easy to install. Great for my cats that at 25 pounds each. I needed the large door. Easy to lock them when needed easy to have the door go both ways.

Took a little work for my application since I used it on an aluminum screen door that had solid aluminum at the bottom. After cutting into the bottom of the door, the rest of the installation went well. This was the only door that I found that would fit my screen door and it worked perfectly. Pup loves it, Wife loves it, so I survived another project

Even tho the door is the right size, the lock is on the bottom and has consistently locked our cats out. Had to tape it.

The cat door is a great size, and easy for my cat yo go through. The installation is easy, the door swings easy, and looks great.I would definately purchase it again!

Actually using as a small dog door. The flap is better than the usual rubber ones that stiffen up in our cold winters. My husband improvised in order to put in sliding glass door. Our male puppy is agreeable, but our one year-old female is a bit skittish about it. We are working on that with her. I really like this door and I am glad that I bought it. It was a very reasonable price, thanks a lot.

I like this product, but it's far from perfect. We live in a small space (37ft camper), and ended up putting it next to the front door because that's where it fits. Well, it opens and closes whenever the door opens and closes (something to do with the pressure I think, I'm not sure). It's also just super drafty even when it's closed and rainwater leaks through it. My elderly cat loves sitting in front of it like it's her own personal window though, which I think is great, and I like the ability to lock it and stuff. Cat still prefers to go out the open human door, but she does seem able to open and close this cat door by herself alright. The locking mechanism is plastic and small, and I feel that in general, although this brought a lot of value to our lives, it's really not a particularly sturdy or well-made product.

The cats love it. Easy to install and durable.
