Best Microchip Cat Flap Buying Guide

Deciding whether to buy a classic cat flap or a microchip cat flap depends mainly on how you want to use it. In other words, your buying motivation.
Do you need a cat flap, before a weekend departure so that Gaspard, your big cat, can go out for a walk in the garden and come home whenever he wants, in complete autonomy? 

To offer freedom of movement inside the house to Lili, your beautiful cat, without having to leave all your doors open, do you want to install cat flaps between the different rooms?

Communication door or entry/exit door: two functions that do not require the same characteristics from your cat flap. And let’s not forget the budget. Significant price differences exist between these 2 types of cat flaps.

All About Microchip Cat Flaps – How do they work?

The microchip cat flap is a more elaborate cat door model. The microchip cat flaps operate using battery power or electrical or even 2. Beware of autonomy during your purchase!

They are ideal for filtering the entries and exits of your cat or dog but also to prevent intrusions by cats in your neighborhood – and this function is its main advantage.

This cat flap is equipped with a device that identifies the chip number of your pets. The door opening at the entrance only (for basic models) will be triggered after this recognition. The squatters of your pet’s bed or bowl will therefore stay at the door! No more untimely intrusions and fights, most often at night in your living room!

Microchip pet doors are generally compatible with all types of 9 to 15 digit chips. Some also work with the most recent chip formats, that is, with a code made up of numbers and letters.

Concretely, 2 cases exist:

1. Your companion has been chipped: in this case, all he has to do is move his head forward in the exit tunnel for the chip to be read and his unique code recorded. Some cat flaps offer up to 32 identifications!

2. Your cat does not have an electronic chip implanted by your veterinarian: your smart cat flap also works with radio frequency identification medallions. They contain a chip. You will only have to attach them to the collar of your tomcats. Then, the approach is the same as for a microchipped animal. When your twink is presented in the exit tunnel, the chip of the medallion is scanned and memorized.

Please note: the unique code identification tags are sold separately in sets of 2. If you have more than two animals or your somewhat rowdy kitten regularly loses his collar, be sure to buy 2 sets. Additional budget to plan any time! Count around 12 € for a set of 2 chip medallions.

Particularity: learning time

For this model of the cat flap, you must take into consideration that your kitty or doggie will have to enter a tunnel to exit and wait a few seconds for the door to unlock with a slight “click”. Some animals, more fearful than others, may take longer to adapt to this model than to classic models. You will then have to be patient and provide a large package of treats. Rest assured, it is exceptional that an animal categorically and definitively refuses to take this path to freedom!

2-way filtered microchip cat flap

There are models that offer so-called “dual scan” input and output filtering. Indeed, imagine the following case: you have several cats and wish to restrict the outward movements of some of them: a sick twink or a cat in heat not yet sterilized, etc…. Nothing’s easier! You can set your cat flap so that it unlocks on exit only for certain of your companions.

The higher-end models of microchip cat flaps generally have the option “two-way filtering: entry and exit”.

Another criterion that will allow you to choose the model suited to your expectations!

On what criteria to choose?

To decide on your purchase, carefully analyze the 4 selection criteria that I have selected. They will certainly guide you towards the best purchase, the one perfectly suited to your needs. The main thing is you and your cat satisfaction!

The descriptive sheets of the products offered or the photos of the many models of cat doors for sale are not always very precise. It is very easy to misguide your choice. I, therefore, draw your attention to the following selection criteria:

  • Cut
  • Closing system
  • Convenience of use
  • Ease of installation


The first criterion is obviously the size of the opening of the cat flap. It seems obvious, but it is often a major source of purchasing errors.
Read the descriptive sheets of the different products you are viewing. The exterior dimensions of the cat flap, useful for its installation as well as those of its opening are generally indicated there.

External dimensions: they relate to the size of the frame. They will determine the dimensions of the cutout of the support on which you want to install your cat flap: door, wall, bay window, patio door, etc. Some cat doors are sold with a cutout template. Very useful not to miss it!

Internal dimensions: they represent the size of the space reserved for the passage of your pet.

Your big cat might find himself a little cramped when taking the path to the exit!

Some suppliers also indicate what weights, sizes, and even leg height of your companions correspond to the interior dimensions of their cat flaps. This is very useful information to aim for the right size. By choosing the passage size perfectly suited to your cat or doggie, you will avoid many disappointments: obligation of return and exchange, loss of time with deferred use, etc. . 

The worst being the cutting of a hole in your door or your window for a cat flap unusable by your 4-legged friend! Be careful! Make the right choice of passage size!

Note: some models exist in different sizes. For a few euros more, you can benefit from the larger size and sometimes additional options.
Do not hesitate to ask for more detailed information if you have any doubts. For an online merchant site, simply send your questions via the dialog box to the seller. The response is usually quick. Do not forget to consult the opinions of previous customers. They are a significant source of useful information!

Closing system

You need to differentiate the locking systems to regulate the entries and exits from those which eliminate the repeated flapping of the leaf of your cat flap, in the event of bad weather and wind. These cause noise pollution that over time is likely to become unbearable, not to mention prolonged exposure to unpleasant drafts.

Closure against drafts and “valve effect” 

The different models of cat flaps are generally equipped with magnetic latches (magnets) effective to avoid the flapper effect in high wind or stormy situations!

Which locking system to choose to control entry/exit movements?

Classic models have manual or electronic locking systems.

For classic models, this manual system allows closing in 2 positions (open / closed) or 4 (open / closed / closed on exit / closed on entry). You can therefore authorize or block the opening of the cat flap, but you will not be able to filter incoming or outgoing animals.

Electronic chip door models: thanks to a very simple configuration to set up: a press of a button and the scan of the chip are enough, you operate a selective access control either in 1 direction: the entrance, or in both entry/exit directions.

With the two-way locking option, you manage the access of some of your pets to the outdoors.

Thus, you put an end to unwanted intrusions from other neighborhood animals or unwanted outings! No more turf wars with brawls in your house, squandering your cat’s bowls and smelly urine markings. No more stress for you and your favorite companion!

For smart cat flap models, you can control all the movements of your pets and intruders at any time and immediately.

Convenience of use

Several points must be taken into consideration, whether the cat flap is classic or electronic.

No noise disturbance: opening or closing click or door beating. These 2 sound sources can initially frighten your most fearful twinks and therefore lengthen the adaptation phase. Not to mention that they can be unpleasant for you too.

The quality of the material of the door: it will guarantee its efficiency and longevity, in the event of significant stress or a turbulent 4-legged companion.

The opacity or transparency of the leaf as well as its flexibility. It’s about your pet being reassured. Confidently, he will quickly use this exit or entry door. A transparent door facilitates adaptation to the cat flap.

Some peculiarities relate only to the electronic chip model. Indeed, it is about the autonomy of the power supply. Clearly, for optimal performance, this type of cat flap needs a constant and reliable power source. 

Whether the cat flap works on batteries (4 batteries or electricity), if the door control no longer works for lack of power, it will be useless to you. In addition, if you find yourself having to change the batteries every week because they drain very quickly, you multiply the risk of breakdown and your budget.

Also, ensure the autonomy data provided by the seller and a thorough cleaning of the battery receptacle as well as its protection against water and dust infiltration.

Ease of installation

The pet doors are all designed for quick and easy 3-step installation. However, a cutting jig can be of great help to the less confident DIYer!

1. Measure

You need to be sure that your cat flap is in the right place. Indeed, the opening must be at a good distance from the ground and adapted to the measurement: height belly of your tomcat / ground. Your darling must be able to access the passage very easily.

2. Cutting

If your cat flap is delivered with a cutting template, this operation will be easy. Otherwise, apply yourself in taking the measurements and identifying the dimensions of your cat flap. Mark the measurement points and connect them using a felt-tip pen to draw your cutting frame on your support.
Jigsaw or drill, you will need depending on the nature of the support of your cat flap. On a glass surface, if you do not have the right tool, call a specialist.

3. Secure

Once you have verified the positioning of the cat flap in the correct direction, secure it securely. For this use screw and screwdriver. In no time, your cat flap will be installed.
