"Kitty Korner is an Amazing invention. Allows Cats to have their own space without leaving a door partially open... Keeps dogs and little kids out too! Love this design, very nice looking!"

Great door and customer service

I ordered the wrong hinge and they sent me a postage paid return with the right hinge. The door works flawlessly and the customer service was above and beyond good. thank you

Cats love it.

Got this for me really since I sleep days after overnight shifts and got tired of opening the bedroom door to let them in and out. Fast and easy to install. Only complaint is I ordered right hand and they sent a left hand hinge that was actually stamped with an R for right hand. Used it anyway because I figured we’d keep it open anyway, but if you’re looking to open and close it pay attention to the stamped letter. But we love it, no more getting up for the cats and they no longer wait on us. Win win.

Love these! Great customer service too :)

Love that I am able to close my door now at night and no scratching! The only suggestion for improvement I would have is to potentially trim the corner of the hinge off so it doesn't stick past the door almost into the frame. If you have an angle grinder you can cut it off, but otherwise it sticks out
