Kitty Korner Cat Door (Lefthand Kit) The Original Patented Kitty Korner Slidelock Hinge Designed to Work for Interior Doors.

The media could not be loaded. We wanted a classy option to allow our cats in & our of our bedroom where there food is kept. Most of the options we saw were cheesy or tackey. Until I found this!Passage: Both of my cats fit easily through the passageway. One of them is a little on the heavy side, but he has no problems. Plus, I didn't have to teach them to push a flap with their noses. Very large cats might squeeze through just a little. However, that could be easily solved by adjusting where the original cut is made. The open flap is supported by velcro (provided) & although I'm not a fan, it works well. Cutting a larger portion of the door shouldn't have an effect on the hinge, but you might need to fasten the open flap with more than 1 square of velcro.Sound: My mother in law lives with us & enjoys watching TV late at night, very loudly, in the living room next to our bedroom. When closed, this keeps the sound barrier as if there's no cat door at all. Plus I don't have to hear a plastic flap swinging everytime they come & go.Installation: Easy project for someone with minimal skills. Getting the screws perfectly flush with the hinge is hugely important for functionality. I was very nervous (mainly because I cut the top of my first door by mistake & had to buy another door) but the YouTube video & written instructions were enough to successfully guide me. Also, the hinge has multiple screw holes to chose from, so you don't have to worry about what the internal configuration of your door looks like. One of the combinations of options is bound to work for you. The seam is visible while the flap is closed on the outside, but I suspect a bit of white paint will make it almost invisible.Sturdiness: Considering I have the hinge supported by only 4 screws (they provided 6 & I could have chose to use all of them) I'm very happy with it. We don't have kids that will be pulling on it or slamming the door. There's no reason it won't last for years.IMPORTANT: I have a solid-core door. I don't know if this will work with a hollow door.Also, when installing the flap portion of the door you must alight the top/edge cuts. Do not center the flap to the raw edge of the door. Upper edge of the door should align with the upper edge of the flapDon't forget to use a spacer while marking holes for the flap. You have to account for the hinge itself & you can't mark your holes while the flap is sitting flat on the door.All of that was shown in the video, but not stated out loud.Overall, I could not have made a very choice. I'm thrilled.

The media could not be loaded. This kitty corner has completely changed our bedtime routine — for the better! Installation was a breeze (took maybe an hour), and it looks sleek and clean against our door. I used to have to leave the bedroom door cracked at night so our cat Oscar wouldn’t pitch a fit — he’s mastered the art of opening doors and screams if shut out. But leaving it open meant dealing with hallway light and noise all night.Now? Total peace. Oscar comes and goes as he pleases, and I get a dark, quiet room. It’s sturdy, subtle, and works exactly as promised. If your cat’s a drama king or queen with a lock-picking streak, this little addition is a lifesaver. Couldn’t be happier with it!

This is very cool. Good directions. Easy to install. Looks good. Has been working well to keep the dogs out of the cat food/liter area. Would like for the kit to pay more attention to the little details. The piece of velcro to hold the door up and open is lame. Too small. Not sticky enough to the door and not grippy enough to each other. Make it a complete kit and include an alcohol wipe to prep the surface before applying a larger velcro patch.

Worked really well on a door with a a design. Good size, full size cats have no problem getting through it. Does not change how to door closes. Easy to open and lock into place. Clear install instructions also a video online

Pros: Love the concept of lockable hinge! And the neat/simple look of this “origami” cat door solution.Cons: not for hollow core doors. There’s nothing to drill the screws into. I solved it by dugging out the few exposed cardboard cells, then glueing two pieces of solid wood inside the door cavity. I attached the hinge to those. There’s ZERO room for error! You gotta install this PERFECTLY, otherwise the door and cut off corner won’t align and the locking mechanism won’t work (the corner will be “flapping”). Also better to install the screws in offset pattern. If you screw them in a mirroring pattern, they tend to rub on each other, preventing the locking mechanism.In retrospect, given how much finecking this product required to work somewhat properly, I’d opt for [a much cheaper] non-locking hinge and installing magnets inside the hollow core. Likely similar effort, but for less money.This product would definitely work way better with a solid wood door. I think advertising it for use with a hollow core door is misleading.

Outstanding product, wish I had found it earlier. So I have two cats..need I say more. I've tried propping the door open with so many other devices, but once I began renting my spare room out, I knew I needed to find a better alternative so I could shut & lock my door. This corner was super easy to cut and install. Great directions, but tiny, so make YouTube your friend. The hardest part was taking the door off, but even that was so easy. Everything was done myself - the door is not heavy, simple to cut. One of my cats is a chunk...wondered if he'd make it thru - piece of cake for him. Now that the cats have mastered the go-thru, they play with each other thru the cutout. Cats be cattin. Great purchase. Mine was a 'right side' order

Don’t buy these for hollow doors, even if they recommend it.These are flimsy, and will ruin your hollow door. Without center bracket support, these bend and come out easily with very little wood to screw into.I’m trying to glue inserts into my door now to make these work, but I’m very disappointed.
