2. SureFlap Dual Scan Microchip Cat Flap.

As all cat owners know, our feline friends have unique personalities, preferences and needs. So, while one adventurous pet may be a menace out hunting, another more timid moggy may prefer to stick to its own territory and rarely bring in any animal it has caught.

Designed for multi-cat households, the SureFlap DualScan microchip cat flap is designed to help you manage your cats’ needs individually, despite them sharing a single cat flap.

The gadget reads a pet’s microchip or SureFlap RFID collar tag every time they go in and out of the flap, and lets you program it to keep certain cats inside, while allowing others out. In this way, you could keep any troublemakers inside at night, while allowing more chilled-out felines outside for a moonlit stroll. The cat flap can be programmed for up to 32 cats, although this would make it as busy as Clapham Junction.

While the gadget isn’t particularly attractive, it is simple to set up with one-button programming, and offers incredible flexibility for multi-cat homes, making life a little easier so that there’s more time to play with your pets. It can be installed in doors, windows and walls (with the aid of accessory kits sold separately) and is powered by four AA batteries which last up to 12 months – although probably not if it is being used by 32 cats!

The cat flap has a manual four-way lock for security, which can be used to keep programmed pets in or out, and is handy for when you go on holiday and want to lock up your home. There’s also a safety mode that allows kitties breaking their curfew to get back inside if they manage to escape through an open door or window.

Guide to Buying a Microchip Cat Flap.

When buying a microchip cat flap it is important to be certain that you are buying a cat flap that suits your requirements, in order to ensure that all you and your cat’s need are catered for we recommend that you make sure you have the answers to the following questions before making your purchase:

Selective Entry & Selective Exit.

Selective Entry is a feature that you (should) find on every single microchip cat flap. This is configured to your cat’s microchip and allows it to come in but prevents other cats from coming in.

Selective Exit is a less common feature which not every microchip cat flap has. This is a feature which is useful if you have more than one cat in your home. It allows you to set the cat flap to one (or more) cat out while preventing your other cat from going out. This can be useful if you have young kittens or you have a cat that is sick.

Cat Flap Size.

Cat flaps vary from model to model, while they typically don’t get much bigger than 250mm wide, it is worth paying attention to the size if you have a very large cat or you wish to use the cat flap for a small dog.

Is Your Cat Micro-chipped and is your Microchip Compatible with your Cat Flap?

It is not necessary for your cat to be micro-chipped to use a microchip cat flap, however if your cat doesn’t have a microchip you will need to use an RFID tag on their collar.

Most, but not all, microchip cat flaps support these so make sure you know if they do support them and ensure that you purchase some as they may not be included by default.

If your cat is microchipped it will have either a 15, 10 or 9 digit code.

The most common type is the 15 digit code.

Most cat flaps cater for all different types of code however some only work with the 15 digit code so make sure you check (in our handy table at the top of the page) before you buy.

If you are not sure how many digits your cat’s RFID microchip has you can check at your local veterinary centre.


Most cat flaps operate on 4xAA batteries, however some can also use a mains adapter.

Typically batteries on most modern models will last for at least 6 months with heavy use, up to 12 months if you have no more than a couple of cats.

Why Should You Buy a Microchip Cat Flap?

Most cat owners will have experienced the shock of uninvited stray cats coming into their home through a cat flap. Sometimes this can be an amusing surprise, but in other cases, it can mean havoc in the home. Not only can these cats fight with your pet and break your valuables, but these curious cats can also mess in the house. You’ll need the aid of your handy hoover to tidy up.

Standard cat flaps can also let rats and foxes inside overnight as they forage for a meal. Cat food left out on the kitchen floor proves irresistible to these hungry creatures.

Of course, this is no reason to restrict your beloved cat’s freedom. As a result, many people are choosing microchip cat flaps which will only grant access to your kitty, while staying firmly locked shut in the face of potential intruders.

These innovative microchip cat flaps allow your kitty to come and go as they wish, giving you and your pet peace of mind. Microchip cat flaps are very easy to install using a power drill and a jigsaw. It can be fitted in doors, walls, and windows. You can even quickly program them to work with multiple kitties if necessary. They are also very easy to buy online through Amazon.

How to Train a Cat to Use a Cat Flap.

If you are yet to put your new cat flap, there are a few things you can do first to boost your cat’s confidence.

Give your cat the opportunity to check out the cat flap before fitting. Let your cat investigate it and sniff it. If they have seen it before installation, this may ally some of your cat’s concerns.

Make sure you install it at a convenient height for them to use. To find out the best height for your cat, measure the distance from your cat’s belly to the floor. This is the correct height to install their new cat flap for optimum ease of use.

Once you have fitted the cat flap, here are some tips to best train your kitty to use it:

  • Hold the flap open at first. This helps your cat to see and smell the outdoors and realise there’s a new exit from the home.
  • Go outside and push your hand through the cat flap with some treats. Once your feline smells the cat food, slowly pull your hand back, leading them through to the other side.
  • Adding your cat’s scent to the new cat flap is a clever way to boost their confidence. Take a cloth or hand mitt and wipe it over your cat. Then rub this onto the cat flap.
  • No matter how frustrated you get, never force your cat through the cat flap. This will just make them even more scared and they will not trust you again.
