Tired of finding stray cats or neighborhood raccoons raiding your home through your regular cat flap? If you have an indoor cat you want to keep safe, or multiple cats with different outdoor access levels, a standard flap just doesn’t cut it anymore.
Quick Answer: The SureFlap DualScan ($226.91) is the best microchip cat flap for multi-cat households because it offers individual exit control—you can let some cats out while keeping others safely indoors. For budget-conscious buyers, the Closer Pets Microchip Cat Flap ($79.99) delivers reliable selective entry at less than half the price, though without exit control features.

Top 5 Microchip Cat Flaps Reviewed
1. SureFlap DualScan Microchip Cat Door – Best for Multi-Cat Control
Est. Price: $226.91
Rating: 4.0/5 (2,387 verified reviews)
Best For: Multi-cat homes with individual exit permission control
Microchip Compatibility: All common microchip types
Why We Recommend It
The SureFlap DualScan stands alone in its ability to set individual exit permissions for each of your 32 registered cats. This means you can prevent indoor-only cats from escaping while allowing your outdoor cats full access—a feature no other flap on this list offers.
Unlike standard microchip flaps that simply let your cat in and out, DualScan’s revolutionary dual-scan technology reads your cat’s microchip twice: once on entry (permission granted) and again on exit (where YOU control whether that specific cat can leave). For households with a mix of indoor and outdoor cats, this alone justifies the premium price.
The 4.0/5 rating from 2,387 reviews shows solid long-term reliability, with users consistently praising the selective exit control as “a game-changer for keeping indoor cats safe.”
Key Features
- DualScan Technology: Reads microchip on entry AND exit for individual cat control
- Selective Exit Control: Set different rules for each of your 32 registered cats
- All Microchip Types: Works with AVID 9-digit, ISO 10-digit, and FDXB 15-digit chips
- Simple One-Button Programming: Adding new cats takes 30 seconds
- Battery-Powered: 4 AA batteries with 12-month life; low battery indicator light
- Weather-Resistant Design: Sealed edges prevent drafts and rain penetration
- Door Opening: 4.75” H × 5.625” W—fits most cat sizes
Pros & Cons
Pros:
- ✅ Only flap offering individual exit control per cat
- ✅ Proven SureFlap reliability with 25+ years in market
- ✅ Works with all major microchip standards
- ✅ Battery life easily reaches 12 months in normal use
- ✅ Installs in seconds without tools for most doors
Cons:
- ❌ Premium price ($226.91) vs. basic entry-only flaps
- ❌ More complex setup than standard microchip doors
- ❌ Requires 4 AA batteries (not included)
- ❌ Doesn’t offer wall mounting like some competitors
Bottom Line
For multi-cat households where access control matters, the DualScan is the only choice. If you have one indoor cat and one outdoor cat, the ability to lock the indoor cat inside while letting the outdoor cat roam freely is invaluable. The 4.0/5 rating and 2,387 reviews prove this isn’t a gimmick—it genuinely solves a real problem cat owners face.
Best for: Multi-cat homes (mixed indoor/outdoor), selective exit control, SureFlap ecosystem users
Skip if: You only have outdoor cats, want budget entry-only, or prefer a simpler flap
2. SureFlap Microchip Cat Flap – Best Overall for Reliability
Est. Price: $164.82
Rating: 4.1/5 (3,391 verified reviews)
Best For: Standard selective entry with proven 25-year track record
Microchip Compatibility: 9, 10, 15-digit microchips
Why We Recommend It
The original SureFlap Microchip Cat Flap is the gold standard for selective entry—used in thousands of homes and recommended by vets across the US. Its 3,391 verified reviews and 4.1/5 rating show unmatched long-term reliability compared to newer competitors.
Unlike basic flaps that let any cat with a microchip enter, SureFlap learns your specific cats’ IDs and blocks everyone else—keeping strays, neighborhood cats, and wildlife completely out. The simple one-button programming means adding your cats takes 30 seconds.
While it lacks the DualScan’s exit control feature, for many single-cat or indoor-outdoor households, entry control is sufficient. The RFID technology has been refined over 25 years, making this the most time-tested option available.
Key Features
- One-Button Programming: Learn up to 32 cat IDs in seconds
- RFID Microchip Reading: Works with 9, 10, 15-digit microchip standards
- Stray/Wildlife Blocking: Only registered cats can enter
- Low Battery Indicator: Red light flashes when batteries need replacing
- 3-Year Warranty: Covers manufacturing defects
- Door Opening: 4.75” H × 5.625” W—standard size fits most cats
- Battery Life: Up to 12 months on 4 AA batteries
Pros & Cons
Pros:
- ✅ 3,391 reviews prove long-term reliability (more than any competitor)
- ✅ Entry control keeps strays and wildlife completely out
- ✅ Simple one-button programming
- ✅ Works with all common microchip types
- ✅ Mid-range price ($164.82) between budget and premium options
- ✅ 25+ year proven track record—recommended by veterinarians
Cons:
- ❌ Entry control only (no exit control like DualScan)
- ❌ Batteries not included
- ❌ Door opening size may be snug for extra-large cats (18+ lbs)
- ❌ Older design (newer options have more features)
Bottom Line
The original SureFlap microchip flap remains the most reviewed and proven selective entry door on the market. If you want rock-solid reliability with 25 years of refinement, 3,391 verified reviews, and a feature set that just works, this is it. The lack of exit control is only a limitation if you have mixed indoor-outdoor cats.
Best for: Proven reliability, entry control, standard door installation, all microchip types
Skip if: You need exit control, want newest features, or have extra-large cats
3. Cat Flap Fever Custom Cat Door Window Insert – Best for Renters & Aesthetics
Est. Price: $189.00
Rating: 4.7/5 (189 verified reviews)
Best For: Renters, window installations, energy-efficient homes
Microchip Compatibility: All microchip types (custom lock option)
Why We Recommend It
Cat Flap Fever solves a major problem: most renters can’t install permanent cat doors. Their custom window insert installs in 2 minutes without tools—no drilling, no permanent modifications, and completely reversible. The 4.7/5 rating from 189 customers shows exceptional satisfaction despite being the least-known brand on this list.
The 1/4” insulated plexiglass with premium foam weatherstripping actually outperforms standard door flaps in energy efficiency. Winter heating bills won’t skyrocket from drafts like they do with basic flaps. Choose the microchip lock option to get full selective entry from a window—a unique approach that works even in apartments and condos.
Custom-made in Georgia, USA, each insert is measured to fit YOUR window perfectly, ensuring gaps that other flaps can’t accommodate.
Key Features
- Custom-Fit Design: Measured to fit your specific window opening exactly
- Microchip Lock Option: Choose selective entry for security
- Tool-Free Installation: 2-minute install, completely reversible for renters
- Insulated Plexiglass: 1/4” thick with premium foam weatherstripping
- Energy Efficient: Blocks drafts better than door-mounted flaps
- Made in USA: Handcrafted in Georgia with premium materials
- Color Options: Clear plexiglass or white for aesthetics
Pros & Cons
Pros:
- ✅ Highest rating (4.7/5) among all microchip flaps reviewed
- ✅ Perfect for renters—no permanent installation required
- ✅ More energy-efficient than door flaps (insulated plexiglass)
- ✅ Custom-fit ensures perfect fit with no gaps
- ✅ Unique window-based approach opens options for apartments
- ✅ Removes completely if you move (no damage)
Cons:
- ❌ Custom order required (not in-stock standard sizing)
- ❌ Requires measuring and ordering process
- ❌ Mid-to-premium price ($189)
- ❌ Window installation may not be ideal for some homes
- ❌ Limited reviews (189 vs. 3,391 for SureFlap)
Bottom Line
If you rent or value energy efficiency, Cat Flap Fever is the clear winner. The 4.7/5 rating (highest on this list), tool-free installation, and superior insulation make it worth the custom ordering hassle. For renters tired of losing security deposits or environmentally-conscious homeowners sick of heating/cooling loss, this is the smartest choice.
Best for: Renters, window installations, energy-efficient homes, apartments and condos
Skip if: You need permanent door installation, want instant shipping, or prefer proven mass-market brands
4. Closer Pets Microchip Activated Cat Flap (360) – Best Budget Pick
Est. Price: $79.99
Rating: 3.8/5 (321 verified reviews)
Best For: Budget-conscious buyers with standard doors/walls
Microchip Compatibility: ISO and AVID standard microchips
Why We Recommend It
At $79.99, the Closer Pets flap is the most affordable selective entry microchip door without sacrificing core functionality. It recognizes up to 30 pets with ISO and AVID microchip standards, features a 4-way rotary lock for additional control, and includes a fully weatherproof design with magnetic closure.
The 3.8/5 rating from 321 reviews is honest—this is a solid budget option without premium bells and whistles. Users consistently report reliable entry control, with the main trade-off being simpler programming and no smart features like app control or battery indicators.
The 4-way rotary lock (in & out, in only, out only, locked) adds versatility that other budget flaps lack, giving you manual control even if your cat isn’t wearing its collar properly.
Key Features
- 4-Way Rotary Lock: In/out, in only, out only, or fully locked modes
- Microchip Recognition: Up to 30 pet IDs with ISO and AVID compatibility
- Versatile Installation: Door, window, UPVC, or wall installation
- Fully Weatherproof: Brush-sealed flap with magnetic closure prevents drafts
- Simple Programming: One-button operation (though less intuitive than SureFlap)
- Budget Price: Most affordable selective entry option at $79.99
Pros & Cons
Pros:
- ✅ Best value at $79.99 (less than half the DualScan price)
- ✅ 4-way lock adds manual backup control
- ✅ Weatherproof design with magnetic closure
- ✅ Supports 30 pet IDs (double some competitors)
- ✅ Works in doors, windows, and walls
- ✅ Good entry control for the price
Cons:
- ❌ Lowest rating (3.8/5) suggests reliability inconsistencies
- ❌ Doesn’t work with all microchip types (ISO/AVID only, not FDXB)
- ❌ Simpler build quality vs. SureFlap’s 25-year refinement
- ❌ Wall installation requires self-lining up to 85mm thickness
- ❌ No battery indicator light
Bottom Line
For single cats, small budgets, or as a backup flap, the Closer Pets delivers solid entry control without premium pricing. The 4-way lock adds practical versatility that justifies the choice over even cheaper alternatives. However, the 3.8/5 rating warns that quality control varies—some units work great, others have issues. If you get a good one, it’s a steal; if you get a bad one, returns are easy through Amazon.
Best for: Budget-conscious buyers, single-cat entry control, door/wall installation, ISO/AVID microchips
Skip if: You have FDXB microchips, want premium reliability, or need exit control
5. Cat Mate Microchip Activated Cat Flap Bundle – Best for Wall Installation
Est. Price: $92.98
Rating: 5.0/5 (1 verified review)
Best For: Wall-mounted installations, small-to-medium cats
Microchip Compatibility: Microchip or ID disc activated
Why We Recommend It
The Cat Mate bundle includes both the microchip flap AND an Elite Wall Liner—saving you the hassle of buying them separately. This is the only entry-only option with built-in wall installation support, making it ideal if you’re cutting a cat flap through an external wall rather than a door.
The 5.0/5 rating comes from only 1 verified review, so take that with caution. However, the bundle’s value proposition is strong: you get selective entry + wall mounting hardware for less than the Closer Pets flap alone ($79.99), plus wall liner extensions for tunneling through thick walls (up to 50mm sections included).
The 4-way rotary lock (in/out, in only, out only, locked) provides the same manual backup control as the standard Closer Pets flap, just with professional wall-mounting support.
Key Features
- Complete Bundle: Flap + Elite Wall Liner (308) included in one purchase
- Microchip or ID Disc: Works with microchips or optional ID collar tags
- 4-Way Rotary Lock: Full access control (in/out, in only, out only, locked)
- Wall Installation Ready: Includes wall liner extension sections for thick walls
- Weatherproof: Magnetic closure and brush-sealed design
- Small-to-Medium Cats: 5.71” × 5.71” opening (suitable for cats up to 15 lbs)
Pros & Cons
Pros:
- ✅ Best value for wall installation (includes liner, saves $30+)
- ✅ 5.0/5 rating (though limited sample size)
- ✅ Bundle approach simplifies shopping for wall-mounted setups
- ✅ 4-way lock provides manual backup control
- ✅ Lowest total price ($92.98) for a complete wall solution
- ✅ Wall liner sections included (normally sold separately)
Cons:
- ❌ Only 1 verified review—extremely limited feedback
- ❌ Small flap opening (5.71” × 5.71”) limits to small-medium cats under 15 lbs
- ❌ No exit control (entry only)
- ❌ Wall installation requires cutting (not for renters)
- ❌ Limited information available vs. established brands
Bottom Line
The Cat Mate bundle is an excellent choice if you’re doing wall installation AND want to save money by buying the liner together. The 5.0/5 rating is encouraging, though the tiny sample size (1 review) means you’re taking a small risk. The small flap opening (5.71”) is the main limitation—this won’t fit Maine Coons or other extra-large breeds. For typical-sized cats going through an external wall, this is the best value option.
Best for: Wall installation, small-to-medium cats, budget buyers, complete setup needs
Skip if: You have large cats, need door installation, want extensive reviews, or need exit control
How to Choose the Right Microchip Cat Flap
1. Microchip Type Compatibility: Check Your Cat’s Chip
The confusion: Microchips come in three formats—and not all flaps read all types.
- AVID (9-digit): Older standard, still common in the US
- ISO (10-digit): European standard, increasingly common
- FDXB (15-digit): Newest format, becoming standard in US shelters
What to do:
- Call your vet and ask which microchip your cat has
- Most modern flaps (SureFlap) work with all three types
- Budget option (Closer Pets) only reads AVID and ISO—if your cat has FDXB, this won’t work
- When in doubt, choose SureFlap for universal compatibility
2. Entry vs. Exit Control: Do You Need Both?
Entry control only (what most flaps do):
- ✅ Keeps stray cats and wildlife OUT
- ✅ Cheaper ($80-165)
- ✅ Works for outdoor cats
- ❌ Can’t prevent your indoor cat from escaping
Entry + Exit control (DualScan only):
- ✅ Lets you prevent specific cats from leaving
- ✅ Perfect for mixed indoor/outdoor households
- ✅ Keeps indoor-only cats safely inside
- ❌ Costs more ($226.91)
- ❌ More complex setup
Choose entry-only if: You have only outdoor cats, only indoor cats, or trust your indoor cat to stay put.
Choose entry + exit if: You have one indoor and one outdoor cat, or want maximum security for a nervous indoor cat.
3. Installation Location: Door, Window, or Wall?
Door Installation (easiest):
- Works in wooden, UPVC, metal, glass sliding doors
- Fastest to install (5-15 minutes)
- Most flaps support this (all 5 options reviewed)
Window Installation (renter-friendly):
- Cat Flap Fever custom inserts fit windows
- Tool-free, completely reversible
- Energy-efficient (insulated plexiglass)
- Great for apartments/condos
Wall Installation (permanent):
- Requires cutting an opening in exterior wall
- Cat Mate bundle includes wall liner for this
- Best for homes with solid external walls
- Permanent solution (not for renters)
4. Microchip Reading Distance: Standard ≈ 10cm
All microchip flaps read from approximately the same distance (~4 inches or 10cm). This is the RFID standard—no significant differences between brands. Your cat will need to approach the flap closely enough for the chip to be read. With RFID collar tags (for cats without chips), the distance is the same.
5. Battery Life & Maintenance: Plan for Replacement
- SureFlap models: 12 months on 4 AA batteries (standard)
- Closer Pets/Cat Mate: Also 12 months on 4 AA batteries
- Cat Flap Fever window insert: Uses standard batteries too
- What to expect: With 3-4 cat entries/exits daily, batteries last 10-14 months
- Pro tip: Mark your calendar 11 months after installation to replace batteries before they die
6. Budget Breakdown: What You’re Really Paying For
| Model | Est. Price | Best For | Trade-Offs |
|---|---|---|---|
| Cat Mate Bundle | $92.98 | Wall install + budget | Small flap, entry-only |
| Closer Pets | $79.99 | Budget entry control | 3.8 rating, AVID/ISO only |
| SureFlap Standard | $164.82 | Proven reliability | Entry-only, mid-price |
| Cat Flap Fever | $189.00 | Renters, energy efficiency | Custom order, window-only |
| SureFlap DualScan | $226.91 | Multi-cat exit control | Premium price, complex setup |
Common Mistakes to Avoid
Mistake #1: Buying Without Checking Microchip Type
The problem: You buy a Closer Pets flap, but your cat has an FDXB (15-digit) microchip from a recent shelter adoption. The flap won’t recognize your cat—complete waste of money.
The fix: Call your vet or shelter FIRST. Confirm the exact microchip type (AVID, ISO, or FDXB) before ordering. When in doubt, choose SureFlap for universal compatibility.
Mistake #2: Forgetting Batteries Aren’t Included
The problem: Your flap arrives, you install it, and realize there are no batteries. Shipping delays mean your cat can’t use it for days.
The fix: Order 2 sets of 4 AA batteries with your flap. Install one set, keep the backup. Total cost: ~$8-12.
Mistake #3: Ignoring Flap Size for Large Cats
The problem: You buy the Cat Mate bundle (5.71” opening), install it, and your 16-lb tabby gets stuck trying to squeeze through. Totally unsafe.
The fix: Measure your cat’s body width at the shoulders. Add 2-3 inches for wiggle room. SureFlap opens at 4.75” H × 5.625” W—standard size fits most cats. For large cats (18+ lbs), you need a full-sized dog door flap, not a cat-specific model.
Mistake #4: Not Accounting for Wall Thickness in Wall Installation
The problem: You cut a hole in your 4-inch external wall, but the flap frame doesn’t reach across the full thickness. Gaps around the edges let in wind and pests.
The fix: Measure your wall thickness before buying. Cat Mate bundle includes wall liner extensions (50mm sections) that tunnel through thick walls. For standard 3-inch walls, most flaps work; thicker walls need the liner.
Mistake #5: Expecting Total Draft-Proofing From Any Flap
The problem: You install a microchip flap expecting it to be as sealed as a regular door. Wind still whistles through when the flap is closed.
The fix: No flap is 100% draft-proof—the moving parts create small gaps. For maximum insulation, choose Cat Flap Fever’s custom window insert (1/4” insulated plexiglass with foam weatherstripping). Door-mounted flaps will always lose some heat/cooling.
Frequently Asked Questions
Can I use a microchip flap if my cat doesn’t have a microchip?
Yes. Every flap on this list supports RFID collar tags (sold separately, ~$10-15 each). Your cat wears the tag on its collar, and the flap reads it just like a microchip. The tag triggers the same selective entry.
Better option: Get your cat microchipped at the vet (~$25-50, one-time). It’s permanent (lasts the cat’s life), can’t be lost, and shelters scan for microchips if your cat escapes.
Do microchip flaps work with all door types?
Yes, mostly.
- Wooden doors: All flaps (install directly)
- UPVC/metal doors: All flaps (with slight variation)
- Glass sliding doors: All except Cat Flap Fever window insert (which uses windows specifically)
- Walls: Cat Mate bundle (includes liner) or any standard flap with wall liner addon
- Windows: Cat Flap Fever only (custom window insert)
Check the product specs for your specific door material, but all 5 models work with standard residential doors.
How long do microchip flaps last?
Typical lifespan: 7-10 years with normal use.
- Moving parts wear out: The locking mechanism and flap hinge eventually fail
- RFID readers degrade slowly: Reading distance doesn’t decrease noticeably for 5+ years
- Weather damage: Exposed flaps in harsh climates (extreme heat/cold/salt) may fail sooner
Most owners replace flaps due to wear (hinge failure) rather than RFID failure. Quality brands like SureFlap last 8-10 years; budget brands may fail by year 5.
Can I install a microchip flap in a window?
Standard cat flap flaps: No—they’re designed for doors and walls, not windows.
Exception: Cat Flap Fever custom window inserts are purpose-built for windows. They use plexiglass inserts with integrated microchip locks. This is the ONLY window-specific option reviewed here.
What’s the difference between “selective entry” and “selective exit”?
Selective entry (all 5 flaps except DualScan):
- Reads your cat’s microchip to let them IN
- Cannot prevent them from going OUT
- Your cat can exit freely anytime
Selective exit (DualScan only):
- Reads your cat’s microchip on ENTRY and EXIT
- You set individual exit permissions per cat
- Example: Let your outdoor cat exit, keep your indoor cat trapped inside
Real example: You have Fluffy (indoor cat) and Mittens (outdoor cat). With DualScan, you register Fluffy’s chip with “exit blocked” and Mittens’ chip with “exit allowed.” Both can enter, but only Mittens can exit.
Will a microchip flap keep out raccoons and possums?
Partially. Microchip flaps prevent TAGGED animals (your cats) from bringing in strays. But raccoons and possums can’t wear microchips. However:
- Most wildlife avoids entering strange homes unless motivated by food
- Microchip flaps have small openings (~4.75” H) that larger animals can’t fit through anyway
- Raccoons are smart but don’t trigger RFID readers—the flap opens only for registered microchips
Better defense: Secure your garbage, remove food sources, and the wildlife typically stays out. A microchip flap’s main job is blocking OTHER CATS—and it does that brilliantly.
Do microchip flaps drain batteries quickly in cold weather?
Slightly. Battery drain increases in freezing temperatures, but 12-month estimates account for this. In very cold climates (below 0°F), batteries may drain faster.
Real impact: Most owners see 10-12 months in cold climates, 12-14 months in moderate climates. Plan to replace annually regardless.
Can I lock a microchip flap completely (keep all cats inside)?
Yes. Most models include a manual lock mode:
- SureFlap models: Sliding lock (prevents flap opening entirely)
- Closer Pets/Cat Mate: 4-way rotary lock includes “locked” position
Use this when you have visitors with pets, during vet recovery periods, or when you want total door control. The lock overrides microchip readings entirely.
