Review on PetSafe Microchip Cat Door, RFID Multi-User Access for up to 40 Pets, 4-Way Locking, Weatherproof, Easy Install, With Hardware Kit - Ideal for Cat Litter Box or Pet Feeder Privacy. by Kayla Mccants

My cat is microchipped so it will be perfect. I forgot that I needed 2 extension sleeves, but I ordered them. We are waiting for an electrician as the installation site requires replacement wiring. Since 121419 the door has finally been installed. My only issue was that when ordering 2 hub extensions, no more screws were sent. The original door was designed for 4" thick walls, and my walls are 6" thick. That's why I needed 2 sleeves. So the first screws weren't long enough. Additional screws must be supplied for additional sockets. In order to fit the door with new sleeves, some unnecessary jolting work had to be done.
