Hakuna Pets Ultra Clear Pet, Cat and Dog Door with 4-Way Locks for Screens, Glass Doors and Windows up to 0.6" Thick, Small, Clear

In remodeling our house, we needed our cat to be able to easily access different areas so we could keep the old doors closed because of the temperature differences. It wasn't bad to install. It does work well. Air still leaks some, but is way better than keeping the doors opened. It would be ok on an outside door, but be aware it doesnt seal completely. It has a magnet at the bottom that keeps the door in the closed position. I would purchase again. The lock works, but I have not used it. Don't want to freak out my skittish cat. She likes to do zoomies through them.

This pet door is much nicer than other regular pet doors i've purchased. Looks very well made, fits nicely together with the weatherstrip. Looks great and operates easily.

We like the door, my cat lays in front of it and can still see out. When she goes out, the door locks open and lets flies and bugs in. So I have to go behind her and make the flap come down.

My cats use it daily. Its thin and sturdy

Poor quality, slides down screen leaving gaps

With a slightly different installation process this will work on a window screen. We wanted something that would not be an eyesore in our loft office space. So clear plastic was highly preferred. Our cats like to go in and out of that window for their evening prowling but we didn't want flies coming in this summer, so the screen needs to stay on and not get tore up by persistent cats. I've included photos of us installing. My husband outside me inside, we screwed it in place with two of the three screws. Then put slices in the screen to allow it the slack needed to fit together, front and back. It telescopes together. Then he installed the third screw and tightened the other two screws. Last, trimmed off the excess screen so the door swings freely. Both of our cats are fans! It did take the 5 year old, big brother more time to trust it wasnt going to smack him. Little brother, 1 year old, has no fear. Also, the window still closes after installation, which we tested BEFORE installing.

I was afraid my cat wouldn't like pushing this open with his head, but the door swings easily & the magnet is just strong enuff to hold the door closed. Once he got the hang of it, he's like a little kid going in & out. I love that the entire door flap & frame are clear since I installed it in an acrylic panel & set it up in the open window so my window pane wouldn't have to be altered. It's not an eye sore & it doesn't block the view. His majesty can look out & decide if he wants to partake in the out of doors.

My husband built this for our rescue kitty. We ordered this door for him. When he was first testing it out.... his little paw got caught as he was experimenting with pushing a little at a time. I believe he may have lost a little if his nail from it.... but we kept telling him to ‘push’ and he learned to use his head. Now he loves when I go to open up my bedroom window.... he is right out the cat door to his catio! Door works great!

nice product for summer or sheltered door or window.
