Review on RIKOUNAN 4 Way Locking Cat Door - Quiet Pet Doors for Cats - Large Interior/Exterior Cat Flap Door - Easy Installation Premium Door for Cats & Small Dogs by Gabriela Alexander

This cat door was easy to install with a pencil, drill and jigsaw. The valve forms a good seal keeping cold/warm air out on one side, but the same function can also injure your cat. If your cat bangs his head hard on the door to get through, you'll be fine. If you have a curious cat (all cats), they will inevitably paw at the new door and clap their hands. Like one of those paper toe traps, your cat sticks her paw in a little, and then when she tries to pull the paw back, it gets trapped under the valve, and the more the cat panics and pulls and howls, the more it gets valve pushes it. Paw. I'm just glad I was standing 10 feet away when poor one-eyed Captain Jack got his paw stuck and panicked. I released it without hurting the paw. After this incident, I immediately cut open and removed the plastic holding the flap. I now have a framed cat entrance through my door without a cover. Buy this door but please throw away the lid so your kitty doesn't get snagged.
