Best Microchip Cat Flap: Buyer's Guide

When browsing for the best microchip cat flap options, you will see that, like other items on the market, there are features, issues, and reasons to use the different versions.


Many of the models will have similar features. Some of the most common ones are as follows.

4-Way Locking System

Many of the microchip cat flaps on the market will have a 4-way locking system. This system allows you to set the cat flap to allow access in, out, both, or neither. 

Selective Entry/Exit 

There is also a selective entry and exit feature. This feature, unlike the 4-way locking feature, allows you to select WHICH cats are allowed to exit or enter. By programming which chips to let in, out, or both, you can effectively manage who comes and goes.

Multiple Cat Recognition

Most models will recognize as many as 25 cats, some as many as 40. This feature makes these products a good choice for not just home applications but also an excellent option for cat rescue operations and pet boarding businesses.

Battery Operated

The ability to run on batteries and a battery life indicator makes it easy to monitor and maintain, with most models needing 4 AA batteries. Most batteries typically last 12 months but may need to be changed sooner if more cats use the door.

Problems with microchip cat flaps

Some of the most common issues with the microchip cat flaps are that they stop working. Having your cat stuck on one side of the flap when he wants to be on the other can be frustrating, so keeping an eye out for these common causes will help.

Battery Issues

Either misalignment or low battery life can cause the flap not to work correctly. Make sure to check the battery life and whether or not they are correctly seated.


After some time, there may be hair and dirt build-up on the sensors, which can prevent the ability to read correctly.

Electrical Disturbances

Because the sensor that reads the microchip uses a sensitive signal receiver, flickering lights and other electrical disturbances can interfere with its ability to read the chip.

Types of Cat Flaps and Doors

So now that you know a little about what to look for with a microchip cat flap, we can compare them to the other types of cat flaps on the market.


These are the original style of flaps. They can be locked, and some even have the 4-way lock feature. They are the cheapest option, come in multiple sizes, and don’t require any power. These models, however, do not have selective access, which can result in random animals accessing your home.

These are essentially the traditional cat flaps but with a lock that is deactivated by having your cat wear a collar with a magnet. These tend to be a little pricier than the traditional model and can be problematic if your pet removes the collar because of discomfort. In comparison, the microchip flap doesn’t require the collar and prevents the possibility of being locked out.

These models use a collar sensor that can be RFID, infrared, or high-pitched sound sensors. Unfortunately, these sensors require both a battery for the sensor on the flap and the collar, making it essential to monitor the battery life of both items. The microchip, however, does not need a battery, simplifying the situation slightly.

Size of Cat

While looking for the best microchip cat flap, considering the size of your cat(s) will be a priority. Ensure your pet can comfortably get through the door to prevent the furry folk from becoming deterred from using the portal.


Like everything on the market, comparing to get the best bang for your buck will ensure you can get the features you want for the best price.

Ease of Installation

Something else to consider is how easy the flap is to install. A lengthy, confusing programming or installation process can be frustrating enough to deter even the most determined.

Anything Else To Consider?

A few things to also consider is whether or not this flap will be allowing your pet from room to room or outdoors. Will it be covered by a porch or directly in the elements? Deciding on how weather resistant the unit needs to be will prevent headaches down the road.
