PetSafe Pet Screen Door - Heavy Duty, Tear- & Puncture-Resistant Dog & Cat Mesh Flap for Extreme Climates - Storm Door Compatible - Small - for Dogs & Cats up to 30 lb

- this is the only option doggy door that can be installed directly to the sliding door screen (I guess window too if you have cats), I got other more expensive ($160) option in the past that requires removing part of the screen, rolled it back to the gutter, and drill directly to the door. The installation of it is so much easier compare to other one.Of course it’s not as solid, pretty- but for what it’s worth, I think it’s good enough.My two dogs are small, so the small door was sufficient and not dragging down the screen door and make it flimsy.- installation instruction was a joke, but there are videos available. It’s hard to tell where to cut since both my screen and frame are both black. Also they slide around a lot. It’s also very difficult to get the two frames to clicked, it took me a frustrated 30 min- even closing the two frames on its own was not easy, let along laying it flat with a stretchy screen. That was very frustrating.- I didn’t use the screw provided. Once I hammer the frames together, didn’t look super secure but I prayed it works… cause I tried the screw and it broke the plastic frame. Maybe if I made a pilot hole it would be ok??? But it hasn’t fall apart this far- anyways you get what you paid for. It’s ok

I live in a fifth wheel RV so cutting hole in the door really was not an option. I'm remodeling the old thing and replaced the screen in the door which had been torn (with my dog and cat running through the hole along with flies and these terrifying Gulf Coast flying roaches * shudder.) As I was pondering how I might create a pet door on the screen door, I ran across this item on amazon. Ordered it that day, on my doorstep the next, installed 15 minutes later. What a time to be alive!It was incredibly easy and intuitive to install I pretty much looked at the instructions thought they were ridiculously complicated sounding, so I threw them away and installed it in what was clearly the only way it could be installed.Do take notice on which side the lock sliders are on because once it's in place I'm thinking you can't take it back out without tearing the screen up. And that locking mechanism... It's not some big sturdy lock it's not going to keep the raccoon out or a determine dog but neither will a screen. I would have preferred that they had a lot slider on both sides of the screen. This item gets five stars all the way around. Seriously folks it provides a pet door in a screen, super easy installation, does exactly what it's supposed to do. magnetized bottom works perfectly to keep the bugs out. And if you've ever seen one of these giant flying palmetto bugs you would know how important that feature is. All for under $20.

We installed this PetSafe door on a brand new screen door before we hung our new screen door onto our house. This was fairly easy to install since we installed it while our new vinyl screen door was not yet installed and we could lay it flat on the patio. It would be very difficult to install without the screen door lying flat. The grooves inside the PetSafe door frame half made it easy to run a blade through our screen door’s screen fabric to cut out the rectangular opening needed for the PetSafe door. The screen fabric inside the swinging door is the screen fabric from PetsSafe and not from our screen door yet it matches ours well. We had to line up one half of the PetSafe door frame on one side of the screen with the other half of the PetSafe door frame placed on the opposite side of the screen and then hammer the halves together to fit closed with the screen fabric between them. We had to hammer the rubber mallet around the circumference maybe 10 times or so before we got all gaps to close between the front and back sides of the Petsafe door frame around the nylon screen hole we cut out. The PetSafe door hinge swings the PetSafe door freely and easily with no real resistance.The lock feature locks either both directions of the swing or just one direction depending on how we set it. We installed it so the pegs of the lock have to be set while standing outside and we’re not sure if that’s a mistake or not, but as we are not likely to need it, that doesn’t matter to us.Now and then we see gaps between the two sides of the frame open up that we pinch closed again. We didn’t use any glues between the frame halves and we weren’t instructed to, but if the frames start having trouble staying pinched together that will be our backup plan. While it appears the PetSafe door is resting on the frame of our screen door, it isn’t. It is lined up near it and is just hanging onto the screen fabric.It really saved us money to install this onto a new screen door ourselves rather than buying a screen door with a pet door already built into it. Our 2 cats got used to it in a couple days and they love it. We are very pleased with this purchase.¡Update! - around 2 weeks after installing it, our active kitten charged through the door and knocked it off the screen so I knocked a star off our rating. We went to our backup plan and put glue gel in the track side of the frame and, while the screen door was still on its hinges, we lined up both sides of this frame (one person on either side of the door) and squeezed it closed around the screen hole it had been on. We couldn’t get it completely squeezed tightLy together around the 4 sides of this pet door frame because the screen door was vertical. I am sure we could have done better if we’d taken it down and laid it horizontal but we’re hoping with the glue it will be good enough to hold. so far so good, it still looks nice and operates well.

Had to re-screen the door to the screen house my Dad and I built 30 years ago and this was a really cheap way to add a cat door. Worked out very well. Would have liked some selective security but just needed basic access. This door is cheap and works well, I like it a lot.
