SureFlap MicroChip Cat Flap from Sure Petcare (alternatively the SureFlap Microchip Pet Door for larger cats) is a revolutionary, battery-powered cat flap which reads your cat's existing identification microchip, only unlocking for them. With just a push of the button, the SureFlap cat flap saves your cat's chip number. Up to 32 microchip numbers can be stored in the device memory, so it is perfect for multi-pet homes. If your cat is not microchipped, the cat flap can be activated with an RFID collar tag. The door opens and shuts automatically as your cat goes through the flap. The SureFlap cat flap from Sure Petcare also has an easy-to-use manual 4-way lock, so you can control which direction the flap opens.
