Review on Optimal Cat Door with Integrated Grooming Brush - Spacious Access for Adult Cats 🐱 up to 20 Lbs - Effortless Installation, Detailed Instructions, Secure Screws & Screw Caps Included by Denise Rose

After reading the reviews I was a little worried about the height of the opening. My big cat is a good size but I think she is actually medium sized. The area I wanted to use has a door that was notched a little at the bottom so that added about 1/3 inch. He goes in and out well. My smaller offspring cat has no problems either. Great chocolate labs. I'm wondering what's going on and I think I wasted my time and money for nothing :) Installation was easy. The door is hollow and it took 20 minutes with a jigsaw to pull out, cut and screw the frame. Very easy.
