It works. I have it on the inner door of my bedroom. Both of my cats are fine with it. Only 2 small problems on my part. You must have the perfect door position to install the locks properly. Not very practical, like simple rotary knobs. My older cat figured out how to lift the door to get out, even when it's locked to get out, it comes out. Very easy installation, just need to adjust the lock better.
