Thin Cat Door for Windows, Pet Doors and Sliding Door, Safety Pet Door with 4 Way Lock, Weatherproof Cat Flap for Thin Door and Wall(Medium, 7.7 * 7.5 * 0.78in)

So far, works like intended. Easy to install and worth the money.

It works well. slightly larger than the other one we had but slightly more flimsy. My mom's cats are on steroids and if they wanted, it would not prevent hate and destruction from entering or exiting. But it is also for the garage door which we usually leave unlock. the hairs surrounding the rim to prevent air flow needed regluing but not a big deal.

I built my own window unit using this door, and it works perfectly! I will say the only downside is that the locking slides sometimes Close during my cat going in and out and he can’t get back in, so I have to remove them when I’m not home.

I need something that would work for my catio entrance windows. It did! Super easy to install

I bought two of these so I would have a front entrance and back entrance. One to be used as an escape door if needed. I did have some issues like other reviewers in the door not shutting the whole way, I just trimmed up and removed a bit of the caulking so to speak on the swing part of the door. That seemed to take care of the problem. All in all, it was a good purchase if you are willing to modify it a bit, I would buy it again.
