Window with cat flap will give cats free access to their outdoor catio when fully built. Love it and built well, but I was under the assumption it had a window section on each side of flap but it only has 1 window.

I don’t usually right reviews but this product is really good. My cat just loves to be outside but it was getting to be a pain letting him in and out all the time. This cat door is very solid and stays in the window very well. My cat is not the brightest so it took him a couple weeks to figure it out, but now he loves it. He is in and out all of the time. He likes to sleep with us and sometimes I will wake up at two in the morning and he is gone, when I wake up later, he is back in bed. He wants to go out in the middle of the night and probably around. Just make sure you cut a dowel to size and secure the window. Other than that it is great. I think the best part is that the cat stopped doing number two in his cat box and barely even uses it for number one. I think he just goes outside for the whole business now which is fantastic.

Video is of the first time he tried it. Jojo is much larger now but still flies in and our through the door to a screened in porch. I hear him go out overnight on patrol and come in for some kibbles when he feels like it. I love giving him his freedom.

Took my kitty a bit to get used to this, with me holding the door open for him the first couple of times, but now he’s a pro and we both love it! It’s super easy to install with the springs on the sides. I don’t really use the door locking feature because my kitty finds it confusing, like why he can sometimes get out but not others, and I found the lock to be a little flimsy /finicky, but overall love this window flap and would totally buy again.

A little expensive but worth it. Very well built. Easy to install, and solid. I should of bought this sooner. Now I never hear my cats whining to let them out only to feed them now.

Well made and easy to install. Took the cats less than an hour to figure out how to use it.

Works. Fast and easy to install. Snug and a secure fit. Took less than an hour for my cats to use it. Especially my one very timid cat. He's afraid of everything. But master the in and out of the swinging door. Can lock it several ways. In and out. Out only or in only. Or no exit at all. I rent and have metal screen doors so put a hole in them was not an option. When I move I can take the cat door with me. Weather tight too.

This is by far the BEST option for your cats or dogs for a window pet door. We did not want to cut out a big hole in the actual patio door to install a pet door. So, we found out this option and gave it a try! and it's been working amazing. Our cats used it immediately, it got a 4-way lock system which is great because at night we don't like them to roam free in the neighborhood so we just lock it. I am so happy that I am not anymore the 'doorman' for them. They are now free to go and get in. It is worthy every penny. The materials are excellent, and super easy to install.
