The SureFlap Microchip Cat Flap is the best SureFlap microchip pet door for most households. It carries the highest rating in the range alongside the largest owner base, it unlocks for your pet’s existing microchip so no collar tag is needed, and it runs on 4 AA batteries for up to 12 months without any wiring. The bigger Microchip Pet Door suits small dogs, and the Connect and DualScan models add app control and per-cat exit rules.
A fair disclosure before we start: our team did not physically test these five doors, so everything below comes from published manufacturer specifications and from what long-term owners report in forum threads. Where a figure is a manufacturer claim, like the 12-month battery life or the 6 11/16 in by 7 in pet door opening, we say so rather than presenting it as a measurement of our own.
The idea behind every model is the same and it is worth stating plainly, because it explains why this brand keeps coming up in searches. A conventional plastic flap swings open for anything that pushes it, including a neighbour’s cat, a squirrel or a raccoon. A microchip pet door keeps a scanner in the tunnel, reads the chip already implanted under your pet’s skin, and releases an electronic lock only for numbers you have programmed in. No collar, no tag, no digging.
Sure Petcare builds exactly five of these doors, split into a compact cat-door size and a larger pet-door size, with and without app connectivity. That makes the decision narrower than it looks. The questions that actually separate them are pet size, how many cats you have, whether one of them must stay indoors, and whether you want your phone to tell you when the flap moves.

1. SureFlap Microchip Cat Flap, White – Best Overall
SureFlap – Sure Petcare Microchip Cat Flap, White, Scans Pet’s ID on Entry, Check Your Cat’s Size,Flap Opening is 4 3/4” (H) by 5 5/8” (W)
★★★★★★★★★★Flap opening 5 5/8 in W x 4 3/4 in H
4 AA batteries, up to 12 months
Reads 9, 10 and 15 digit chips
- Uses the cat existing microchip so no collar tag is needed
- Blocks stray cats raccoons and rodents
- Sealed flap edges cut draughts better than loose flaps
- One-button programming with three lock modes
- Three year warranty
- Opening is small so larger or heavier cats may struggle
- Flap click can startle cats and needs training
- Battery drain and lock stiffening after 3 to 4 years
This is the door most people end up with, and for good reason. Owners with 18263 reviews rate it 4.1 out of 5, which makes it the best-evidenced pick in the whole range. The specification sheet is short because there is very little to get wrong: an RFID scanner in the tunnel, a lock that releases for up to 32 stored identities, and four AA batteries that the manufacturer rates at up to 12 months of use.
Long-term owners describe the same outcome repeatedly. Put the flap into learning mode, let your cat push into the tunnel once so the chip is read, and from that day the intruder pressure stops. Several people describe it as quietly solving the 4:30am cat-door routine within a fortnight. The sealed flap edges also sit tighter than a loose-swinging plastic flap, which owners notice in winter.
What you trade for that simplicity is size and longevity. The 5 5/8 in wide by 4 3/4 in high opening suits an average cat, and heavier or larger cats report having to squeeze. The other consistent theme in reviews is that everything is smooth for the first three or four years and then the lock stiffens and the batteries drain faster.
There is one design constraint worth internalising before you buy. The scanner sits at the top of the tunnel, so your cat must put its head in rather than just walk up to the flap. That is not a flaw, it is the security model, but it is the reason some cats need a week of encouragement before they will commit.
Is the scan delay a fault or normal behaviour?
The pause before the flap releases is normal, not a defect. Owners who have had doors for years describe the same two-step feel: a push, a short wait while the reader registers the chip, then the flap swings free. Cats that bolt through in a straight line can outrun it, which is why the training advice on the next section matters more than the delay itself.
Some owners with nervous cats prop the flap open for the first few days so the cat can walk through an open hole and meet no moving plastic at all. Others feed the cat right at the tunnel mouth. Both work, and neither compromises the lock once the prop is removed.
Who should skip this specific model?
Skip it if your cat is a large or heavy Maine Coer type who already struggles with a standard cat flap, because there is no way round the fixed 4 3/4 in height. Move up a size to the Microchip Pet Door rather than forcing the fit.
Also skip it if your problem is keeping one specific cat indoors. This model scans on entry only, so that cat can still walk out and simply not be able to return. That single limitation is what the DualScan exists to solve.

2. SureFlap DualScan Microchip Cat Door – Best for Multi-Cat Homes
SureFlap DualScan Microchip Cat Door – Door Opening is 4 3/4″ H x 5 5/8″ W
★★★★★★★★★★DualScan reads chip on entry and exit
Per-cat exit permissions
4 AA batteries, up to one year
- Keeps indoor-only cats inside while others go both ways
- Compatible with all common microchips
- Stores up to 32 pet identities
- Blocks stray cats and wildlife
- Installs in doors windows or walls
- Same compact 4 3/4 in by 5 5/8 in opening
- Costs more than the single-scan flap
- Programming per-pet exit rules takes setup time
The DualScan solves the one problem a single-scan flap cannot: it lets you choose which cats may leave, not only which cats may come in. It scans the chip as the cat approaches from outside and again as the head comes back through on the way out, then applies the permission you set for that specific animal. A cat marked indoor-only is refused on the exit side of the tunnel, while the outdoor cats pass in both directions as normal.
That sounds obvious once explained, and it is still the most misunderstood feature in the range. Owners repeatedly ask whether a second scan can be scheduled per cat, which tells you the feature is not well advertised. The answer is that you set exit permission per stored identity during programming, up to a maximum of 32 pets.
Where this model is weak is size and price. The flap opening is identical to the standard cat door at 4 3/4 in by 5 5/8 in, so a large cat fits no better here. The rating of 4.0 across 2445 reviews sits a notch below the white cat flap, and the two reasons owners give most often are exactly those two facts.
The battery story is the same as the other cat doors: four AA cells, rated by the manufacturer at up to one year of normal use, with a low battery warning. Programming takes longer than a single-scan door simply because you are assigning exit rights to more than one cat, and doing it in one sitting saves a lot of frustration.
How do you set exit permissions per cat?
Put the door into learning mode, let each cat pass its head through the tunnel in turn, and then set the exit behaviour for that stored identity as you go. You repeat the cycle for every cat you want to control, up to 32. The whole job is a ten-minute job if you have the treats ready and the cats in the room.
Practical tip from owner experience: program the indoor-only cat first while the others are shut in a bedroom. Programming is easier when the cat you are registering is not distracted by three other cats trying to go through at the same time.
When a plain cat flap is the better buy?
Choose the single-scan model if all of your cats are allowed outside and you just want strangers kept out. DualScan earns its extra cost only when at least one cat must be denied exit, or when you want exit events recorded in a log.
There is a second case for it: households where an outdoor cat returns muddy and the indoor cat is not supposed to follow. DualScan handles that without any app, which is a genuine advantage over the Connect version at the same cat-door size.

3. SureFlap Microchip Cat Door Connect with Hub – Best Smart Cat Door
SureFlap Microchip Cat Door Connect with Hub Bundle – Door Opening: The Microchip Cat Door Flap Opening is 5 5/8″ (w) by 4 3/4″ (h
★★★★★★★★★★Hub bundle with Sure Petcare app
Remote lock and unlock,4 AA batteries, up to 12 months
DualScan entry and exit control
- Remote lock and unlock from the app
- Entry and exit notifications on pet movement
- DualScan exit control per cat
- Works with existing microchips
- Three year warranty
- Lowest average rating of the range at 3.8
- Hub and app add setup and ongoing dependency
- 4 3/4 in flap height limits larger cats
This bundle pairs the cat-door size with the SureFlap Hub and the Sure Petcare app, and it is the only model in the range that tells you what happened. Entry and exit notifications, an activity history log, a scheduled curfew and remote locking all come from the Hub, which relays events from the door over your home network.
At 3.8 out of 5 across 1435 reviews, it is the lowest-rated door we cover, and the reason is consistent: the app and the Hub are both the reason to buy it and the reason for the complaints. Setup pairing, dropped connections and software updates are the recurring themes, alongside the same small opening every cat door in the range shares.
One forum behaviour is worth knowing before you commit. A number of Connect owners who found the reader too slow for their cat have simply unlocked the door permanently from the app and use it as a notification-only device. That is a legitimate strategy, but it turns a selective flap into an ordinary one, so decide your tolerance for that risk early.
Owners on the Home Assistant community forum run the Hub over MQTT against a local broker precisely to get away from the cloud dependency, and an openHAB binding covers the same hardware with its own curfew settings. If you already run a self-hosted smart home, the local route exists and is well documented by its community.
Is the Connect upgrade worth the Hub dependency?
It is worth it when you genuinely use the information: a cat on a medication schedule, a diabetic cat you need to know is moving, or a household where someone worries all day about whether the cat got out. Notifications and activity history are the features people mention most often as the reason to keep it.
It is not worth it if the appeal is simply a nicer-looking install. You gain remote locking and curfew control, and you take on a device that needs power, a network route and an app that has to keep working with your phone. Owners who expected the app to be invisible are the ones leaving the most negative reviews.
Which setups should avoid this bundle?
Avoid it if you are renting and cannot cut a hole, because the install work is identical to the standard models but the total cost is not. You would be paying for app features in a door you may have to remove when you move.
Also weigh it carefully if you have more than one cat and only need exit control. The DualScan does the same job without a Hub, without an app and without a network dependency, and it carries a better owner rating.

4. SureFlap Microchip Pet Door – Best for Small Dogs
SureFlap Microchip Pet Door (Brown)
★★★★★★★★★★Flap opening 6 11/16 in H by 7 in W
4 C batteries, up to 12 months
Reads 9, 10 and 15 digit microchips
- Largest opening in the range for small dog breeds
- Keeps stray animals out while a chipped pet passes
- Simple one-button programming
- Standard C batteries with long service life
- Three year warranty
- Highest cost of the SureFlap doors we cover
- Selective entry only so a pet can leave without a scan
- Bulky frame needs a suitable cutout
This is the door to buy the moment your pet is anything other than a cat. The flap opening of 6 11/16 in high by 7 in wide is the largest in the range, and it is the reason small-dog owners rate it 4.1 out of 5. It runs on four C cells rather than AA, which is the manufacturer’s answer to the higher power draw of a bigger motor and a heavier door.
For a maltipoo-sized dog wanting backyard access, this is the model owners actually build around. The programming is the same one-button routine as the cat doors, the microchip compatibility is the same 9, 10 and 15 digit formats, and the warranty is the same three years. Nothing about the core mechanism is a step up or a step down.
The catch is that it scans on entry only, exactly like the standard cat flap. A pet can always go out; it just cannot come back in unless the lock releases. For a dog that is fine. For a large cat that you want to keep indoors during the day, it is the wrong tool, because the only control you have is at the entrance.
The bulkier frame also changes the installation conversation. A 7 in wide opening needs a proper cutout, and if you are working in glass you are already paying for a glazier. Measure the install hole before you commit to this model rather than after.
Do I need the larger model for a large cat?
Usually yes, and owners on the Mumsnet litter tray thread make exactly this point, describing the Microchip Pet Door as slightly larger to allow for bigger cats. If your cat shoulders its way through a standard flap and looks squeezed, the extra two inches of height is the fix that training cannot provide.
Before you order, measure the animal rather than guessing from breed. You want the widest part of the cat to pass through without compressing, and a cat that turns sideways in the tunnel is a cat that will stop using the door.
Who should not buy the pet door?
Skip it if you need exit control, because selective entry is all you get. Households with an indoor cat and an outdoor cat need the DualScan or a Connect model, not a bigger hole.
Skip it for a medium or large dog. A 7 in by 6 11/16 in opening is sized for small breeds, and a dog that has to duck and squeeze will damage the flap and lose interest within weeks. The warranty will not save you from that.

5. SureFlap Microchip Cat Flap – Best Simple Starter
SureFlap Microchip Cat Flap
★★★★★★★★★★Flap opening 4 3/4 in H by 5 5/8 in W
4 AA batteries, up to 12 months
Reads 9, 10 and 15 digit microchips
- Stops intruder cats raccoons and rodents
- Uses the existing microchip with no collar tag
- One-button programming is straightforward
- Long battery life in the first several years
- Draft tight sealed flap edges
- Small opening is hard work for large or heavy cats
- Flap click can frighten cats and takes days to train
- Battery drain and lock stiffening after roughly 3 to 4 years
This is the original in the range, and for a single outdoor cat in an average-sized home it remains the simplest thing that works. It scans on entry, reads 9, 10 and 15 digit microchip numbers, stores up to 32 identities and runs on four AA batteries rated at up to 12 months. There is no app, no Hub and no account to create.
Owners with 3431 reviews rate it 4.0. The pattern in the long-running review base is very consistent: the flap keeps out stray cats, raccoons and large rodents, works reliably for three or four years, and then battery drain and a stiffening lock become the complaints. A small number of buyers also report units arriving with the lock settings out of alignment.
Training is the real work and everyone says so. The click of the releasing flap can frighten a cat badly enough that it refuses the door for days, and in some cases weeks. Treat that as part of the purchase rather than a fault, because a cat that is scared of the flap will find a window or a gap instead.
Against the white cat flap earlier in this roundup, the mechanical specification is the same size and the same battery format. Choose between them on listing detail and finish rather than on function, and check the three year warranty and the low battery indicator are both described for the unit you are actually buying.
How do you train a cat that hates the flap?
Start by propping the flap open and letting the cat walk through a hole with no moving part for a few days. Once that is boring, let the flap move but never let it close on the cat, feeding a treat on the far side so the sound arrives with a reward rather than with being caught.
Then move the prop away gradually and keep treats in the tunnel mouth. Most owners report a normal-looking cat within a week or two. If your cat is new to the house, wait until it is settled before starting, because training competes badly with the stress of a new environment.
What happens after four years of ownership?
Expect to change batteries sooner and expect the lock to feel heavier. That is the consistent long-term report, and it usually shows up somewhere between year three and year five depending on how many pets use the door and how warm the install spot is.
Good news is that support is one of the stronger parts of this brand. An owner who reported a broken locking button on a several-year-old unit had a replacement sent within two days of contacting the company. That kind of response is the practical reason to buy from a brand with five models and a long owner base rather than a no-name flap.

How Microchip Detection Actually Works?
A SureFlap microchip pet door unlocks by reading the RFID microchip already implanted under your pet’s skin, so the pet never has to wear anything. The scanner sits inside the tunnel of the flap, and the electronic lock stays shut until it recognises a chip number you have programmed in.
Programming takes one minute per pet. Put the door into learning mode, let your animal push its head into the tunnel so the reader passes over the chip, and the door stores that number. Repeat for each pet, up to 32 stored identities. From then on, a registered pet approaching from outside is scanned, the lock releases and the flap swings; anything without a recognised number gets a solid door and a few minutes of confusion.
Chip compatibility is broader than most buyers expect. The cat doors and the pet door work with 9 digit Avid Secure, 10 digit FDXA and 15 digit FDXB numbers, and Sure Petcare describes the DualScan as compatible with all common microchips. If your pet is unchipped, an RFID collar tag is the fallback, so you are not forced to book a microchipping appointment first.
One behaviour trips up almost every new owner. Because the reader needs the head in the tunnel, a pet that pushes through at speed can reach the flap before the lock releases and bounce off it. Owners describe a short wait before the flap gives, and some describe their cat sitting back and trying again, which is exactly the intended behaviour. A cat that has been startled once will take longer to trust the door, so build the training in rather than rushing it.
Which SureFlap Microchip Pet Door Is Right for You?
Choose by pet size first, then by how many animals and whether you need exit control, then by whether you want app features. Get that order right and the choice takes about a minute, because there are only five doors and they differ in clear, deliberate ways.
Measure your pet before you pick a size
The cat doors give you a flap opening of 5 5/8 in wide by 4 3/4 in high. The Microchip Pet Door gives you 6 11/16 in high by 7 in wide. Those two numbers are the whole sizing decision, so measure the animal at its widest point and compare it against the opening rather than against a breed chart.
If your cat is large, heavy or already dislikes narrow gaps, buy the pet door even for a cat. Owners with several larger cats describe that model as the one that stopped the daily squeezing. If your animal is a small dog, the pet door is the minimum viable size and there is nothing smaller in this range.
Count your cats and decide who may leave
Only two of the five control which pets may leave. The Microchip Cat Flap, the original Microchip Cat Flap and the Microchip Pet Door let any animal walk out and only control the way back in. The DualScan and the Cat Door Connect scan on both sides and let you refuse exit for a specific cat while others continue to use the door normally.
That decision is worth more than any app feature if you have an indoor cat. If every cat in your home is allowed outside and the only problem is intruders, save the complexity and take the simplest door that solves it.
Plan the install surface before you buy
All five models install in doors, windows or walls, using the same approach: cut the hole, run the tunnel through, and mount the frame. The wall option is the most involved because the tunnel is shallower than a thick wall needs, and tunnel extenders add roughly 50mm each. Owners report measuring their own install and finding the tunnel too shallow, which is the most common installation regret.
Glass is the expensive one and the one buyers are least warned about. A glazed door needs a mounting adaptor, a circular cut of roughly 294 to 320mm, and a replacement panel cut to suit, which means a glazier. Budget for the labour before you commit, because it can easily exceed what you expected to spend on the door itself.
Renters have the hardest version of this problem. If you cannot cut the door, a wall-mounted door on a brick or plaster surface is usually cheaper than a new glass panel, and a conservatory or utility door is often the easiest place to start.
Compare the batteries, not just the battery life
The cat doors take four AA cells and the Microchip Pet Door takes four C cells, and both are rated by the manufacturer at up to 12 months. Batteries are not included with any of them, and they are non-rechargeable alkaline. Budget for a yearly change and watch the low battery indicator, which flashes red.
Long-term owners report that the interval shortens noticeably in later years of service. Treat the first-year figure as the good case rather than the expected one, and check the batteries every autumn before the cold months when the lock motor works harder.
Decide whether the Connect features earn their keep
The Connect models add remote lock and unlock, entry and exit notifications, an activity log and a scheduled curfew through the Hub and the Sure Petcare app. Without a Hub you get the same selective entry and the same DualScan behaviour where it applies, just without the reporting.
Curfew mode is the sleeper feature for people who want a cat kept in overnight. The alternative is remembering to lock the flap by hand before bed, which is the habit most people abandon in week three. If the app is going to be the only thing that keeps your cat in at night, that is a good reason to buy Connect. If it is a nice-to-have, it is a good reason to skip it.
SureFlap or PetSafe?
SureFlap is the stronger choice on long-term owner evidence, app depth and the size range, because PetSafe competes mainly at the single cat-flap tier while Sure Petcare covers cat and small-dog sizes with and without connectivity. SureFlap also has the longer track record of owner reports on four-plus-year durability.
PetSafe is the shorter, cheaper single-door answer and it does the core job of keeping unregistered animals out. If you want one microchip cat flap, no app and no small-dog option later, a PetSafe model is a reasonable spend. If you will still be thinking about a second door, an indoor-only cat or app control in two years, the SureFlap range answers more of those questions with one ecosystem.
Which setup should avoid these doors entirely?
Look elsewhere if your pet is a medium or large dog, because the biggest opening in this range is 6 11/16 in high by 7 in wide and nothing here is sized for a Labrador. Pet owners weighing bigger openings can start with our guide to the best dog doors, though none of those read a microchip.
Also look elsewhere if you need a burglar-proof or fully wildlife-proof barrier. Owners on the r/SurePetcare forum report raccoons and squirrels prying the flap open and leaving even when it is locked, and the flap is a deterrent rather than a defeat. A heavy-gauge door with a separate locking panel is the answer if a determined animal is the real concern.
What these doors will not stop?
It also will not help you if your pet is unchipped and you skip the collar tag. Know the limits before you install, because a door that gives you false confidence is worse than a standard flap you have reinforced with a clip.
Frequently Asked Questions
Which microchip pet door is best?
The SureFlap Microchip Cat Flap is the best all-round choice, with a 4.1 rating across 18263 reviews, selective entry on your pet’s existing microchip and four AA batteries rated at up to 12 months. Choose the Microchip Pet Door for a small dog, and DualScan if one cat must be kept indoors.
Which microchip cat flap is best?
For a single outdoor cat, the SureFlap Microchip Cat Flap is the best microchip cat flap, because it needs no app and no Hub. For a home with several cats, pick the DualScan Microchip Cat Door, which sets exit permission per cat. For app control, take the Microchip Cat Door Connect with Hub.
Which microchip cat flap is better, PetSafe or SureFlap?
SureFlap wins on long-term owner evidence, app depth and choice of sizes, since Sure Petcare covers cat and small-dog doors with and without connectivity. PetSafe is a cheaper single microchip cat flap that does the basic job of blocking unregistered animals. Choose PetSafe for one simple door, SureFlap if you will add an indoor-only cat or app control later.
What are some common problems with SureFlap microchip cat flaps?
The most common issues are a cat refusing the flap because of the click when the lock releases, a small 4 3/4 in opening that big cats struggle with, and battery drain plus a stiffening lock after three to four years of use. On Connect models, Hub pairing and app connectivity are the leading complaints.
What are people saying about the SureFlap Microchip Pet Door?
Owners of the larger Microchip Pet Door rate it 4.1 out of 5 and single out the 6 11/16 in by 7 in opening as the reason it works for small dogs. The common caveat is that it scans on entry only, so a pet can leave without a chip scan, and the frame needs a proper cutout.
Is SureFlap Connect worth it?
SureFlap Connect is worth it if you use the information it gives you, such as entry and exit notifications, an activity log, a scheduled curfew and remote locking. It is not worth the Hub dependency if you only want the flap to work quietly, because the standard and DualScan models do that with no app at all.
Is it worth getting a microchip cat flap?
Yes, if stray cats, other people’s pets or wildlife push through a standard flap, because a microchip door unlocks only for your own registered pets. The common complaint is training: the click of the releasing flap can frighten a cat, and most owners report a week or two of encouragement before it becomes normal.
The Bottom Line on SureFlap Microchip Pet Doors in 2026
The SureFlap Microchip Cat Flap is the best SureFlap microchip pet door for most people in 2026, because it carries the best owner evidence in the range and asks the least of you at install time. Buy the Microchip Pet Door if your pet is a small dog or a large cat, and buy DualScan if one of your cats must not be allowed out.
Only add the Connect models if you will genuinely use the app. Before you click through, measure your animal, confirm the chip format, and work out whether the install means a glazier. Those three checks prevent almost every complaint we found in owner threads. If you are also fitting out a wider pet setup, our picks for the best dog doors, the best automatic pet feeders and the best pet water fountains cover the rest of the setup. For owners who travel with their pets, our best pet carriers guide covers the travel side.
