The best security cat flaps are a must if you’ve got an independent feline that loves its freedom and heading out on its own daily adventures. Microchip cat flaps take away the stress of unwelcomed visitors finding their way into your home. Whether that’s other cats from the neighbourhood, slightly less domesticated furry creatures, or worst-case scenario, skilful burglars using it to try and attain your front door keys.
They will provide that safe entryway for your cat, keep your home free from pests, and give you peace of mind. Plus, you can use it to track when your cat is home, especially helpful if they like to keep themselves, and some are surprisingly affordable for the added security. It's certainly a more affordable option than investing in a pet security camera.

A microchip cat flap will scan when your cat is nearby and recognise their microchip ID. It will then open for your cat and your cat only, and some can even register when the cat flap has been used – great for working out where your cat is or when they last popped out. In the UK, domestic cats have to be microchipped by law, so these microchip cat flaps can work for any cat owner.
We’ve shared some of the best microchip security cat flaps for your home and included some cat flap adaptors to help with the installation.

Best battery powered microchip cat flap
SureFlapAvailable in brown or white to match your door, the SureFlap Microchip Cat Flap is one of the most popular options on the market, coming recommended by 97 per cent of customers on Argos alone, and we can see why. It's compatible with all common microchips and RFID collar tags, and can be installed in doors, walls, or windows - whichever suits you and your kitty!
One of its stand out features is the one-button programming function as customers have said that it makes it easy to use. Customers also find that installation process pretty straightforward, because as we've previously mentioned, it can be installed in a variety of openings to suit your home's needs. The downside is that you don't get alerted when the batteries are close to running out so you'll want to check that regularly to make sure the flap is still working as you expect.
Overall, we're really impressed with the security features and the fact it can store the information of a whopping 32 pets. That way, you can make sure only the familiar furry faces are coming through while keeping any stray animal intruders out.
Pros
- Customers found it easy to use and install
- Can store the information of up to 32 pets so great for multi-pet households
Cons
- It doesn’t tell you when the batteries are close to running out so you'll want to keep an eye on the functionality of this flap regularly to ensure it's still working
| Dimensions: | 14.2 x 12cm |
| Installation and use: | You will need a circular hole in order to install this cat flap. The cat flap can be installed into holes up to 260mm in diameter. It will require four AA batteries, but then it will last up to a year. |
Best microchip cat flap for large cats
SureFlapDesigned especially for larger cats (and small dogs), this SureFlap Microchip Pet Door will keep out intruders but make sure your cat feels very welcome.
Very much similar to the SureFlap Cat Flap we've included above, it's so simple to program up to 32 pet identities on the LCD screen so it gets a thumbs up from us for ease of use. Although customers felt it took their cat a little longer to get to grips with how it works so be prepared for a few teething issues while your kitty gets used to it.
The battery issue seems to have been sorted out from the SureFlap Cat Flap as it also has a battery low indicator on the LCD screen so you know when the batteries need to be switched around. The main reason customers reached for this one as it has extra room for their kitty to go through so if you have a bit of a tubby tabby on your hands, this will ensure it has plenty of space for them to come and go as they please.
Pros
- Battery low indicator so you can see when the batteries are close to running out
- A good size for larger cats (and small dogs) to fit through
Cons
- Customers felt it took a while for their kitty to learn how to use it so be prepared for there to be a bit of a teaching period while they get used it
| Dimensions: | 28 x 26 x 12.5cm |
| Installation and use: | It's easy to install into wood and can also be fitted into glass and walls. This pet door runs on 4 C cell batteries. |

Best microchip cat flap for homes with kittens and adult cats
Sureflapwww.argos.co.uk
The SureFlap Dual Scan Microchip Cat Flap is very similar to the SureFlap Microchip Cat Flap with a microchip or RFID collar tag identification and the fact it can be programmed for up to 32 cats. However, this cat flap is equipped with DualScan Technology so you can set entry and exit permissions for your different animals with each pet being learned at just the push of a button.
There may be occasions where your strictly indoor cat may end up outside as they’ve escaped through an open door or window. These things can happen but the last thing you want is for them to be stuck outside and not be able to get back in. Luckily, this cat flap has an in-built safety mode so your indoor-only pet can use the flap from the outside to get back in the house without being able to get back outside again.
Designed for small and medium-sized cats, this may not be ideal if you've got a larger cat you want to keep tabs on. However, if you’ve got a kitten or average size cats you want to keep an eye on, this will be ideal. Many of the customers have used this for keeping their kittens indoors while their adult cats have been able to roam outside and have found the safety feature particularly useful as they know their kitten’s chip will still be recognised from outside even though they are registered as an indoor cat.,
Pros
- Comes with DualScan Technology to set entry and exit permissions for different pets, useful for homes with kittens and adult cats
- Safety mode ensures that microchips of indoor cats are always recognised from outside so they can get back indoors if they manage to get out of an open window or door
Cons
- It's designed for small and medium sized cats so larger breeds might struggle to fit through
| Dimensions: | 21 x 21 x 14.8cm |
| Installation and use: | Can be installed in wood, uPVC, glass, and walls. Requires four AA batteries. |

FAQS
Is it worth getting a security cat flap?
We definitely think it's worth getting a security cat flap if you're worried about other neighbour cats coming into your home, scaring your cats and even marking your territory by spraying. They'll only allow the cats that are supposed to be there through the flap. They also make for great cat trackers so you can easily see whether they're home or out exploring. Some are smart enough that you can see the times when they leave home and arrive back again so you can understand more about their roaming habits.
How do you put in a microchip cat flap?
If you're putting your cat flap into a glass door or wall, we'd recommend hiring a professional to fit the installation as you'll require specialist tools. However, you can install a cat flap into a wooden or plastic surface of your own accord using a drill and jigsaw.
First of all, you'll need to measure the ideal position of your cat flap so your cat can easily hop through. It should be as high as your cat's legs. Next, using the provided template or cat flap frame, draw the size of the cat flap hole onto your door, before drilling through each corner and connecting the dots using your jigsaw blade.
