Review on Purrfect Portal XL Pet Cat Door: Easy Installation in Minutes for Large Cats (Up to 30 lbs) on Interior Doors - Secure Entryway with Molded Plastic Pass - Includes Instructions & Hardware, White by Celeste Pagtama

If you have the tools needed to install Purrfect Portal I installed it in an hour. I didn't use a stencil, I circled most of the outside. As you can see I placed it in the double doors and centered it on the panels. I bought a large cat portal because this kitty is going to grow up! Portal to access his tray that we placed in the laundry room. Not only did I give Max light in a room that was pitch black at night, I went to Menard's and bought a rechargeable motion detector, a Good Earth night light that I highly recommend, and clipped it to the side of my clothing. Washing machine at cat height.
