What is the best smart cat flap?

In our opinion, the best smart cat flap, currently available, comes in the form of the original Sureflap, which can register the identification microchips of up to an incredible 32 cats – though it's equally suited to homes with just one, or a handful of kitties.

On top of this, it promises easy installation and four-way lock, which makes it extra-secure against potential intruders.

How to buy the best smart cat flap

When it comes to choosing the best smart cat flap for you (and your furry friends) we'd recommend bearing the following factors in mind:

Number of cats

When sourcing the right smart cat flap, you'll need to think about how many kitties you're catering for. Most cat flaps offer entrance for between 25 and 42 cats – more than enough for the average family – but you'll want to make sure you're not getting caught out by a model that offers entrance to too few.

Timer control

Do you want the option to limit when your cats can come in and out of the house? If your cats are scared of the dark, or you don't like the idea of them being out after hours, you'll want to look out for a model with a built in timer.

Selective exit

Perfect for those looking to set different time restrictions for different pets – be that kittens or older moggies who need a little more care – selective exit allows pet owners to alter the entrance and exit rights for each pet, individually.

The best smart cat flaps: Sureflap DualScan Microchip Cat Flap

3. Sureflap DualScan Microchip Cat Flap

Best cat flap for more than one cat: set timers and rules for separate pets, or little ones just starting to explore the world

Best for: Exit permissions
Number of pets: 32
Selective exit?: Yes
Timer control?: No
Power source: 4 x AA batteries
Reasons to buy
+ Set different rules for different pets + Easy mounting 
Reasons to avoid
-No timer control

On first examination, the Sureflap DualScan Microchip Cat Flap is hardly distinguishable from the original Sureflap in our number one spot, and it actually boasts most of the same charms: a 32-cat memory, easy mounting even in glass doors with the use of the included mounting adapter, quick microchip learning function and four-way lock, to be precise.

The one vital difference lies in the ‘DualScan’ part which may make it worth the extra outlay. This enables you to set different permissions for different pets as well as time limits, so younger cats can spend increasing amounts of time outdoors, or small dogs who also use the flap can be kept from going outdoors at night, for example.

It also has dual auto-locks in addition to a four-way manual lock, making it an extra-secure option for those particularly worried about intruding wildlife or stray cats.

The best smart cat flaps: SureFlap Microchip Pet Door

5. SureFlap Microchip Pet Door

Best cat flap for dogs: smarter (and larger) than your average cat flap, this one also works as a doggie door

Best for: Dogs and cats
Number of pets: 32
Selective exit?: No
Timer control?: Yes
Power source: 4xC batteries
Reasons to buy
+ Sized for small dogs as well as cats+ Curfew mode 
Reasons to avoid
-Can't control which animals are allowed in or out

Yet another close relation of the original SureFlap, this SureFlap Microchip Pet Door, perhaps unsurprisingly, is also in possession of a 32-cat memory and secure, long-lasting construction. Its big differences are twofold: first, its size, which allows small dogs as well as larger kitties to use the door, while the microchip functionality ensures larger creatures like foxes are still kept out.

It also swaps the separate permissions of the Sureflap DualScan for Curfew Mode, a built-in timer which programmes the door to lock and unlock at times set by you, so if you’d rather your pets didn’t go a-wandering while you’re asleep, this is a great way to ensure they stay safe.
