Microchip Cat Flap: Features & Questions to Consider

What Size Cat Does Smart Cat Flaps Fit?

There’s no one size fits all microchip cat flap. The smallest product listed above measures 142 x 120 mm while some models have wider fittings measuring up to 248 x 267 mm. It’s up to you to choose a size that is ideal for your cat and door.

A good idea is to measure the size of the cat and add an additional percentage of wiggle room to allow your cat to comfortably get in and out.

How Do Smart Cat Flaps Work?

To use a smart cat flap, it is recommended that your cat has a microchip installed. Each microchip has a unique ID number. But if your cat doesn’t have a microchip, worry not. Most microchip cat flap options also allow the use of RFID.

Next, you will need to program your cat’s RFID or microchip to your microchip cat flap. The cat flap stores the microchips or ID’s data in its memory permanently.

Simply register your cat’s unique code on its microchip (or RFID collar tag) to the flap and you are good to go. Only cats whose data has been stored will be allowed to come in or go out.

Once installed, the flap works by allowing entry (or exit) of only the cats whose data has been programmed. Some options allow you to customize the exact time that a cat can get in or go out.

The flap has sensors that detect when your cat is approaching and automatically opens. If your cats are used to using a normal cat flap, using a microchip cat flap will be a breeze.

However, cats can take some time before they can get used to the clicking sound produced by the flap.

How to I Install a Smart Cat Flap?

Before the actual installation of your smart cat flap, begin by deciding where you’d want it fixed. You can install it in a wooden door, UPVC, or even a glass door.

Installing the cat door on a UPVC or wooden door is easy. It can be done using a few readily available tools, such as a jigsaw. However, if you’re installing the cat flap on a glass door, you’ll need professional help from a qualified glazier.

Every smart cat flap comes with detailed installation instructions. The instructions vary from one brand to the other. Mostly, the installation process is easy and is complete in 30 minutes.
