- Slevoo Cat Door for Window, 10-Min No-Cut Installation, Adjustable Width of 31"-36", Upgraded 4-Mode Knob Lock, Weatherproof Aluminum Frame Cat Door Window Insert for Cats & Small Dogs

My cat constantly pines for the outdoors, especially with spring approaching. She is great about coming back inside, and I do not mind her using the bathroom outside. She is not much of a hunter either, so the local bird population is safe. The problem was that I only have a sliding door to my back deck and no easy way to install a traditional cat door. I found this while shopping on Amazon and decided to give it a try. It fit my window perfectly. All I had to do was build a small step so she could reach it from inside and get down safely on the other side. She absolutely loves being able to come and go as she pleases. The insert itself feels very sturdy, and the door has a locking feature. I do not really use it, but if you have raccoons in your area, it would probably be helpful at night. As far as heat efficiency goes, I am sure it is not quite as insulating as my double pane windows since there is a thin flap in the middle, but I do not feel any drafts coming through. It seems to seal up really well.

So I bought this because I wanted a clean way to give my cats access to their catio without leaving a window cracked open and losing all my heat or AC. I’ve had it installed and in use for a couple of weeks now, and it’s been a huge quality of life upgrade in my house. Installation was genuinely simple. It drops into the sliding window track kind of like a small window A/C unit, and the adjustable sides made it easy to get a snug fit. I didn’t need any tools, and it came with weather stripping and window lock pieces so it feels secure once it’s in place. The frame itself is solid and doesn’t feel flimsy, and the clear panels are a nice touch so the window area doesn’t feel blocked off. The flap works smoothly and the magnetic closure actually seals. I can tell there’s way less draft compared to my old DIY setup, and I like having the 4 lock modes. I use “both ways” during the day, then lock it at night, and it clicks into each setting without feeling cheap. The opening is also a good size. My bigger cat can go through without squeezing or hesitating. The only minor thing is the magnet snap can be a little loud in a quiet house, especially at night when a cat is making a dozen trips like it’s their job. It hasn’t been a dealbreaker for me, just something to know. For the price, it feels well made and renter-friendly since it doesn’t require drilling. If you have a sliding window leading to a patio or catio and you want a sturdy insert that seals up nicely, this one has been excellent.

We are so happy with this Cat Door for our window! Installation was incredibly easy and truly tool free, which was a huge plus. It fit perfectly within the adjustable 28"-32" range, and the aluminum frame feels very sturdy and well made. The high transparency glass looks clean and blends in nicely with the window, so it doesn’t look bulky or out of place. I love the 4 secure lock modes. it gives us full control over when our cat can go in and out. The flap swings smoothly, and our cat figured it out almost immediately. Protecting my pet with the lock as well. It’s solid, secure, and makes life so much easier, no more constant door duty! If you’re looking for a quality window cat door that’s durable and easy to install, this is definitely the one to get. Highly recommend!

I bought an almost identical item recently and it works wonders. You just open the window, place the device inside the frame, and close the window onto it. That's really about all there is to it. This one's just as easy. Your cat should have no problem using the flap, though he or she might need a little coaxing and demonstration. It's easy to close up the door so that the cat can't get out when you need that to be the case. The flap closes flush against the sides so rain and snow shouldn't get in, and I don't even feel the need to make any adjustments for temperature (though this will vary based on location and climate). It's a nice, solid way of letting your furballs get in and out at their leisure. Just PLEASE, if you must let your cat out, ensure that they're spayed or neutered. There are already too many homeless cats out there.

This adjustable window cat door is a smart and practical solution for letting your feline friend come and go without you having to open windows. It’s designed to fit a range of window widths, so no permanent modifications are needed. The magnetic flap with brush-lined edges keeps drafts and debris out while allowing smooth, quiet passage for your cat. The multi-mode locking system lets you choose in-only, out-only, two-way, or fully locked access. Overall, a convenient, flexible, and easy-to-install option for cat owners. What’s great: • Adjustable width fits a variety of standard window openings. • Magnetic flap with secure seal keeps weather and dust out. Durable! • Multiple lock modes give you control over pet access. Easy to use!

Was unable to use this in my windows. So can't say how it works. I am using it as a cat door between my door opening. Works for that. The quality and sturdiness seems great. Would recommend this product if it fits in your window.

I haven’t been able to install this cat door yet, but I got it in preparation for moving into a new house soon. I’m planning to get a catio that will connect directly to a window, and this pet door seemed like the perfect solution so my cats can go in and out freely without me constantly acting as their doorman. Right out of the box, the door feels very sturdy. The aluminum frame is solid, and the transparent flap looks much nicer than the cloudy plastic you see on some pet doors. I also love that it’s adjustable from 32" to 36" because it gives me flexibility for whichever window I end up using. Even though I haven’t used it yet, I’m really impressed with the build quality and thoughtful design. I’m excited to set it up once I move, and I can already tell it will make the catio transition smooth and convenient for both me and my cats. Highly recommend for anyone planning a catio or looking for a simple, window-mounted pet door option!

This window pet door is a clever way to let a cat move in and out without cutting into a wall or door. The adjustable width helped it fit my window, and the frame feels sturdy once everything is in place. The clear panel keeps the window looking neat and still lets light in. Installation was doable but took some careful measuring and adjusting to get it seated securely. The flap works, but my cat needed a little time to get used to pushing through it. It does the job, just not as quick to set up as it first appears.
