How does the LCD display work?

The Cat Mate Electronic I.D. Disc microchip cat flap's LCD display shows cat location, exit lock status, and the low battery indicator.

What's the main difference between this door and the Cat Mate Elite 305 Super Selective cat flap?

The Cat Mate Elite Super Selective cat flap is not a microchip pet door. It requires an RFID collar tag on your cat's collar to give your pet access inside and out. If you have a cat that cannot wear a collar ID, it would not be a good option for you.

Can I install this dog door into a wall?

Yes. The Cat Mate Elite Microchip Cat Flap is self-lining and can be installed into surfaces up to 4" thick, making it great for installing into single and double glazing, doors and door panels, and walls. If installing into a wall that is thicker, you may need to invest in a Pet Mate wall liner.

Does this need electricity to run?

Yes, the elite selective cat door needs battery power in order to work. The door does have a training mode that turns off the microchip and collar tag sensing so that the door works like a manual cat flap.

What are the other 4-way locking cat flaps options out there?

For microchip pet doors, the Sureflap Dualscan is raccoon-proof and allows you to set access controls for up to 32 separate pets. The Petsafe Indoor Cat Flap is non-electronic and also has a 4-way locking feature.
