Installing the "SureFlap" automatic cat door

Unsolicited product review and demonstration of how to install this cat door that only unlocks when it detects the RFID tag in your cat's "chip." We bought this product for a cat who was constantly begging to be let in or out the door. It took our cat about a week to learn how to use the door and, more importantly, understand that he can choose to use it whenever he wants.
