Quick answer: The SureFlap Microchip Cat Flap is my top microchip cat door for most homes: it reads your cat’s implanted chip on the way in, stores up to 32 pets, and has more owner reviews than any other pick here. For a household with many cats, the PetSafe Microchip Cat Door stores up to 40 pets; for a bigger cat, the SureFlap Microchip Pet Door has a larger 6 11/16″ x 7″ flap.
A microchip cat door unlocks only for the cats you program, so the neighbor’s tomcat, raccoons, and squirrels stay outside. I have not tested these microchip cat doors myself; my picks are based on manufacturer specifications and verified owner reviews.

The Best Microchip Cat Doors Reviewed
1. SureFlap Microchip Cat Flap: Best Overall
Prime SureFlap - Sure Petcare Microchip Cat Flap, White
As an Amazon Associate I earn from qualifying purchases. Product details and availability are accurate as of the date/time indicated.
The SureFlap Microchip Cat Flap is the most-reviewed microchip cat door on Amazon, with more than 18,000 ratings. It uses RFID to read your cat’s implanted ID chip and only unlocks for programmed pets. It learns up to 32 identities, and SureFlap sells collar tags for cats without a chip.
It works with 9-digit (Avid Secure), 10-digit (FDXA), and 15-digit (FDXB) chips, and it can go in doors, windows, or walls with SureFlap accessories. Note that it scans on entry only, so any cat can still go out.
Key specs
- Scanning: on entry only
- Pets stored: up to 32
- Flap opening: 4 3/4″ (H) x 5 5/8″ (W)
- Power: 4 AA batteries (not included), up to about 12 months
- Extras: low-battery indicator light
- Warranty: 3 years
Pros
- Huge number of owner reviews
- Works with the three common chip formats
- Door, window, and wall install options
Cons
- Cannot stop a cat from going out
- Flap is small for big breeds
Bottom line: The safe, proven choice for an average-size cat that just needs to keep strays out.
2. PetSafe Microchip Cat Door: Best for Multi-Cat Homes
Prime PetSafe Microchip Cat Door, Interior/Exterior
As an Amazon Associate I earn from qualifying purchases. Product details and availability are accurate as of the date/time indicated.
PetSafe’s door reads your cat’s 15-digit microchip and gives access to your cat and up to 39 other programmed pets, the highest number on my list. Cats without a chip can use programmable collar keys, sold separately.
A manual 4-way lock gives you Locked, Unlocked, Enter Only, and Exit Only. Two magnetic latches and built-in weather stripping help keep out drafts and prying paws. It fits most wood, PVC, and uPVC doors; metal, glass, brick, and wall installs need extra accessories.
Key specs
- Microchip: 15-digit
- Pets stored: up to 40
- Lock: manual 4-way
- Seal: two magnetic latches, weather stripping
- Weight: 1.76 lb
- Warranty: 2-year limited
Pros
- Stores far more pets than most doors
- Exit Only and Enter Only modes
- U.S.-based customer care
Cons
- Listing only mentions 15-digit chips
- Lower average rating than the SureFlap picks
Bottom line: A good fit for a busy home with several cats and a wood or uPVC door.
3. Cat Mate Microchip Activated Cat Flap (360): Best for Glass and Wall Installs
Prime Cat Mate Microchip Activated Cat Flap (360)
As an Amazon Associate I earn from qualifying purchases. Product details and availability are accurate as of the date/time indicated.
The Cat Mate 360 opens with your cat’s microchip or a Cat Mate I.D. disc. Its strength is installation: the listing says it suits single and multi-glazed glass, uPVC and metal doors, walls, and wooden doors, with a self-lining frame up to 85 mm (3 3/8″) thick.
A 4-way rotary lock lets you set in and out, in only, out only, or locked, for example to keep your cat home at night. The flap is fully brush-sealed with a magnetic closure for draft and weather resistance.
Key specs
- Entry: microchip or I.D. disc
- Install: glass, uPVC, metal, wood, walls
- Self-lining: up to 3 3/8″ (85 mm)
- Lock: 4-way rotary
- Power: 4 AA batteries (not included), low-battery indicator
Pros
- Widest range of install surfaces here
- Brush seal and magnetic closure
- Simple one-button programming
Cons
- Listing does not state how many pets it stores
- Fewer owner reviews than SureFlap
Bottom line: My pick when the door has to go in glass or a wall rather than a wooden door.
4. SureFlap Microchip Pet Door: Best for Large Cats
Prime SureFlap-Sure Petcare Microchip Pet Door (White)
As an Amazon Associate I earn from qualifying purchases. Product details and availability are accurate as of the date/time indicated.
This is the bigger version of SureFlap’s cat flap. The flap opening is 6 11/16″ (H) x 7″ (W), which gives large cats, like a Maine Coon, more room, and SureFlap also suggests it for small dog breeds.
It uses the same tech as the cat flap: entry-only RFID scanning, up to 32 pets, one-button programming, and support for 9-, 10-, and 15-digit chips. The listing says it has no app and no timer, and it has over 5,700 ratings.
Key specs
- Scanning: on entry only
- Pets stored: up to 32
- Flap opening: 6 11/16″ (H) x 7″ (W)
- Power: batteries (not included), up to about 12 months
- App / timer: no
- Warranty: 3 years
Pros
- Roomy flap for big cats
- Same proven SureFlap system
- Door, window, or wall installs
Cons
- No exit control
- Larger hole to cut than a standard cat flap
Bottom line: The one to buy if your cat is too big for a standard cat flap.
5. Ferplast Swing Microchip Large Door: Best With a Chip Collar Included
Prime Ferplast Cat Flap with Microchip Swing Microchip
As an Amazon Associate I earn from qualifying purchases. Product details and availability are accurate as of the date/time indicated.
Ferplast’s large swing door reads ISO 11784 microchips and unlocks as your pet approaches. It can memorize up to 30 microchips, and it comes with a collar that has a built-in chip, so you can use it right away even if your pet is not chipped yet.
The swing door opening is 17 x 20 cm (about 6.7 x 7.9 inches), made for big cats and small dogs. A 4-way system sets exit only, entry only, entry and exit, or locked, and the Wind Stopper System helps keep drafts out.
Key specs
- Microchip: ISO 11784
- Pets stored: up to 30
- Door opening: 17 x 20 cm
- Outer size: 26.5 x 16.2 x 31.5 cm
- Lock: 4-way
- Included: collar with microchip
Pros
- Chip collar in the box
- Large opening for big cats and small dogs
- Controls both entry and exit
Cons
- Very few owner reviews on Amazon so far
- Metric sizing, so measure carefully
Bottom line: A good option for a large or unchipped cat, but a less proven product than the others.

How to Choose a Microchip Cat Door
Check your cat’s microchip
Not every door reads every chip. The SureFlap doors list 9-, 10-, and 15-digit chips; PetSafe lists 15-digit chips; Ferplast lists ISO 11784. Your vet or shelter can tell you your cat’s chip number.
Measure your cat
Compare your cat’s shoulder width with the flap opening. A standard flap like the SureFlap Cat Flap suits most cats; large breeds need something like the SureFlap Pet Door or Ferplast.
Entry only or entry and exit?
Entry-only scanning keeps strays out, but any cat can still leave. If you have an indoor cat and an outdoor cat, choose a model with exit control. My best smart pet doors guide includes the SureFlap DualScan, which scans both ways.
Where will it go?
For glass, metal, or a wall, check the listing first: the Cat Mate 360 covers the widest range out of the box.
Install note: Cutting into glass, a wall, or a rented door is a big step. Check with your landlord first, and use a professional for glass and masonry.
Final Thoughts
For most cats, the SureFlap Microchip Cat Flap is the best microchip cat door, with simple entry scanning and a huge base of owner reviews. Choose the PetSafe for many cats, the Cat Mate 360 for glass or wall installs, the SureFlap Pet Door for a big cat, and the Ferplast if you want a chip collar in the box.

FAQ
Do microchip cat doors work with any microchip?
Most read the common formats, but check the listing. SureFlap supports 9-, 10-, and 15-digit chips, while PetSafe lists 15-digit chips only.
What if my cat is not microchipped?
SureFlap and PetSafe sell collar tags or keys separately, Cat Mate works with an I.D. disc, and Ferplast includes a collar with a chip.
Will a microchip cat door keep other cats out?
Yes, that is the main purpose. The door stays latched for any animal whose chip is not programmed.
Can I stop my cat from going out at night?
Yes. The PetSafe, Cat Mate 360, and Ferplast have locking modes for that, including in only, so your cat can come home but not leave again.
