## Description

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

Review: I love it. My cats love it. Solved all our problems. Probably the best cat door in existence. - 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 flap Don'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.
Review: Greatest thing since sliced bread. - Best invention ever. Easy to install. Looks great. Very functional for when I need to lock my cats in my bedroom for whatever reason. Would give it 10 stars if possible.

## Questions & Answers

**Q: What size is the triangular opening?  My cats are extra large**
A: The finished dimensions of the Kitty Korner Door "Flap" are approximately 10" X 14" X 10".  Most people find even their large cats will fit.  If you uncertain take a large cardboard box, cut a corresponding opening in one corner put your Chonk inside and see if they can get out.

**Q: The "flap" is designed to be 10"x14"x10". Is it possible to cut a flap that is 12"x17”x12" to accommodate a taller cat? Or will the hinge not work?**
A: Most residential doors in the US today are hollow core.  The Kitty Korner Door is designed to mount to the normal interior framing in a door.  Increasing the size, not only causes issues with available mounting points but also can significantly change the weight of the "flap".  In addition a larger flap will create more leverage on the hinge and mounting points.  Kitty Korner does NOT recommend increasing the "flap" size to make a larger opening.

**Q: If I order the right swinging door, will it fold up on the inside or the outside of my door?**
A: The Kitty Korner is designed for the "Flap" to fold towards the side of the door where you can see the hinges protruding.  Depending upon the door this side might be considered either the inside or outside depending upon configuration.  It is possible to do a non-standard install where the "Flap" flips AWAY from the hinged side of the door. To do this type of install a modification will need to be made to the doors, door jamb and the opposite kit would need to ordered.

**Q: Can anyone confirm that the "left swing kit" as shown by amazon is the "left korner kit" pictured by the manufacturer?**
A: Yes they are the same. They are intended to be mounted to Left Hand swing doors.

### ⭐⭐⭐⭐ Good item.
*by S***C on October 9, 2025*

My cats and wife love it. Can close the door for some privacy but the moochers can come and go. After using it for 8-9 months it is starting to warp. Not terrible, still does the job, but could be more durable.
