A cat coming through the back door, a litter box tucked behind a closed bedroom door, and an outdoor space that should remain available only to your own cat. A microchip cat door can solve those access problems, but the right choice depends on whether you need selective entry, weather sealing, interior privacy, or simple access for several pets. The options below cover each need, including one microchip-activated model and several practical alternatives for different homes.
The Shortlist At A Glance
PetSafe Deluxe Magnetic Cat Flap White
Purrfect Portal Meow Manor XL No-Flap Interior Door, White
Cat Mate 2-Way-Locking Cat Flap with 50mm Door Liner, Brown
Purrfect Portal Gnome Door for Interior Doors, No Flap and Lockable
Cat Mate Microchip Activated Cat Flap for up to 30 Cats, Grey
Ferplast Swing 5 Grey
Cat Mate 387 Adapter Kit for 360 Microchip Flap
Purrfect Portal Meow Manor No-Flap Interior Cat Door
The Strengths Of Each Pick
The PetSafe Deluxe Magnetic Cat Flap gives a cat convenient access to the house while reserving entry for pets wearing the correct magnetic key collar. That makes it a practical fit for a busy home where a regular flap would allow another cat or an outdoor animal inside. You also control the flap in four positions, so access can suit changing household routines.
Unlike a microchip-activated model, this system depends on a collar key, which keeps setup simple for homes without compatible microchips. The magnetic closing action also helps seal the opening against wind, while the supplied cutting template and guide support installation. For most selective-entry needs, the honest read is that collar-key control offers a useful middle ground.
Positive Points
- Only cats carrying the matching magnetic key can open the flap.
- Four settings cover open, closed, incoming-only, and outgoing-only access.
- The magnetic closure helps limit wind through the opening.
- Useful in homes where you want selective entry without a microchip reader.
Trade-Offs To Consider
- Your cat must wear a compatible collar key, which some cats resist.
- The white finish suits a light-colored doorway better than a dark exterior door.
Key Specs
Made For
This flap suits homes with several outdoor cats that can comfortably wear collar keys and need selective access without microchip programming.
Where Another Pick Suits Better
Cat Mate Microchip Activated Cat Flap suits multi-cat homes that already use compatible implanted microchips and prefer collar-free identification.
A room hidden behind a closed interior door can become far more useful when your cat still has a way in. The Purrfect Portal Meow Manor XL creates that access around a litter box, food area, or private resting space without a swinging flap. For most interior projects, the open passage also removes the flap noise and paw-catch concern associated with many conventional pet doors.
This XL version is designed for cats up to 30 pounds, giving larger cats more room than the standard Meow Manor reviewed later. It fits solid and hollow-core interior doors measuring 1.25 to 1.75 inches thick, with screws and instructions included. Unlike the collar-key PetSafe model, this one controls indoor access rather than deciding which cat may come inside from outside.
Reasons It Performs
- The flap-free opening provides an unobstructed route for paws and whiskers.
- A large opening suits cats up to 30 pounds and reduces the need to squeeze through.
- Screw-secured installation suits both solid and hollow-core doors.
- The opening can be closed to deny access to dogs or children.
Points To Note
- Its large arch shape needs a generous cut-out in an interior door.
- Exterior installation is not its intended use, so outdoor weather sealing is not a stated feature.
The Right Fit
This XL interior door works well for larger cats and households that want a private litter or food room behind a conventional swinging door.
Consider Something Else When
Purrfect Portal Gnome Door for Interior Doors, No Flap and Lockable suits smaller cats and homes that prioritize a decorative, compact appearance.
The Cat Mate 2-Way-Locking Cat Flap is built for an exterior doorway where weather and access control both matter. A brush-sealed flap, magnetic closure, and rain-resistant seal work together to reduce draughts and water intrusion. Compared with the PetSafe Deluxe Magnetic Cat Flap, it does not identify a specific cat, but it gives you three operating states for routine household control.
Its compact 145-by-145-millimetre opening fits small to medium cats, while the trimmable liner accommodates doors or walls up to 50 millimetres thick. Installation can take place in UPVC, metal, or wood, making it a practical choice for a typical exterior door. The polymer construction and silent operation also make it a sensible choice for homes sensitive to repeated flap noise.
Well-Handled Touches
- Three locking states give you clear control over entry and exit.
- Multiple seals help protect against draughts and rain.
- The quiet polymer flap suits bedrooms and busy entryways.
- The trimmable liner simplifies fitting into different surfaces.
Small Caveats
- The compact opening is less suitable for larger cats than the Purrfect Portal XL.
- The opening can be locked, so a misplaced locking setting may deny access.
Technical Sheet
Who Will Love This
This model suits owners of small to medium cats who want a quiet, weather-sealed exterior flap in a UPVC, metal, wooden, or wall installation.
A Better Fit Elsewhere
Ferplast Swing 5 Grey suits mixed-pet homes that also want a flap with four operating settings and a direction indicator.
The Purrfect Portal Gnome Door puts function inside a playful cottage design, making a cat access point feel less like a cut rectangle in a door. Its no-flap construction gives a cat an unobstructed route, while the lockable opening lets you separate a litter area from the rest of the home. That makes it particularly useful in an apartment, nursery, or neat utility room where appearance matters.
The opening is intended for cats up to 20 pounds, so it serves most standard cats better than the larger Meow Manor XL. Compared with that roomier model, the Gnome Door prioritizes a decorative shape and litter-box concealment over maximum passage space. The result feels purpose-built for an indoor privacy project rather than exterior access.
A Favorable Mix
- The cottage-style shape adds character to an interior doorway.
- No flap means quiet, direct passage for the cat.
- The lock lets you control access to a litter or feeding area.
Honest Caveats
- The 20-pound size limit is lower than the 30-pound Meow Manor XL.
- It is designed for interior doors rather than outdoor weather exposure.
- Check the available door area before cutting because the decorative shape requires adequate clearance.
Right Fit For
This door fits indoor homes with cats up to 20 pounds that want a discreet litter-box entrance and a decorative interior feature.
Reach For A Different Pick When
Purrfect Portal Meow Manor XL No-Flap Interior Door, White is a better fit for larger cats that need a wider, more practical passage.
The Cat Mate Microchip Activated Cat Flap is the central choice for a home that wants outdoor access tied to individual identification. Your cat’s microchip activates the opening, while a Pet Mate I.D disc can serve as an alternative identifier. Unlike the collar-key PetSafe, this arrangement lets a cat move through without wearing a special collar, which suits many indoor-outdoor cats.
For multi-cat households, the stated capacity of up to 30 cats allows several registered pets to use the same flap. A manual override provides another route for managing access, while the weather-resistant construction is intended for exterior use. Confirm your cat’s microchip and the installation opening before committing, since the identification method must be compatible with the unit.
What Earns Its Place
- Microchip activation avoids the need for a special key collar.
- Up to 30 cats can be registered for access.
- The flap suits homes with multiple indoor-outdoor pets.
- A manual override adds control beyond normal entry.
Points To Keep In Mind
- Your cat needs a compatible microchip or the supported identification disc.
- Registration and programming add setup steps compared with a basic magnetic flap.
Core Details
Built With In Mind
This microchip flap suits multi-cat homes with compatible chipped cats that need individual exterior access without collar keys.
Another Choice May Suit
PetSafe Deluxe Magnetic Cat Flap White suits a home that prefers simple collar-key control and does not need microchip programming.
The Ferplast Swing 5 works for both cats and small dogs, giving it more household flexibility than the Cat Mate model reviewed earlier. Four locking positions let you allow free movement, restrict entry, restrict exit, or close the passage completely. A direction tab adds a small but useful signal, showing which way a pet last passed through the flap.
Installation works across metal, wood, glass, and masonry, while the wind-stopper system helps reduce draughts. Doors or walls thicker than 5 centimetres require the separately sold trimmable tunnel, so that measurement can determine the final setup cost. For glass installations, factory-drilled holes are necessary for tempered or double-glazed panels.
Useful Highlights
- Serves cats and small dogs through the same compact opening.
- Four settings provide unusually flexible daily access control.
- The direction indicator shows recent passage direction at a glance.
- The wind-stopper helps reduce unwanted air movement.
Possible Compromises
- Thick doors and walls require the optional tunnel.
- Tempered or double-glazed glass needs factory-drilled holes.
- The 13.5-by-13.7-centimetre opening favors smaller pets.
Best Suited To
This flap suits mixed-pet households needing directional control, flexible locking, and installation across several common door or wall materials.
Swap It Out When
Cat Mate 2-Way-Locking Cat Flap with 50mm Door Liner, Brown is a better fit when a compact opening, quiet operation, and a more substantial weather seal are priorities.
The Cat Mate 387 is an installation accessory rather than a complete cat door, and that distinction matters. It is designed specifically for the Cat Mate 360 microchip flap, helping it sit properly in UPVC or metal doors. Instead of buying an unrelated flap and hoping it fits, you get the adapter intended for that door type and reference model.
The required cut-out measures 213 by 262 millimetres, giving you a concrete measurement to check before modifying the door. For a compatible installation, this is a more focused solution than a general-purpose kit. Anyone without the 360 flap, or with a wooden door or wall, should look elsewhere rather than treating this as a universal add-on.
Features That Help
- Made specifically for the Cat Mate 360 microchip flap.
- Supports installation in UPVC and metal doors.
- Provides a clear 213-by-262-millimetre cut-out requirement.
Practical Considerations
- It does not include a complete cat flap.
- Compatibility is limited to the specified 360 model and door materials.
- The required cut-out must fit the chosen door panel.
Feature Facts
Whose Shelf It Belongs On
This kit belongs in a renovation box for someone already fitting a Cat Mate 360 microchip flap into a compatible UPVC or metal door.
Look Elsewhere When
Cat Mate Microchip Activated Cat Flap for up to 30 Cats, Grey is the better starting point when you need the complete microchip-activated unit rather than an adapter.
The Purrfect Portal Meow Manor gives an indoor cat access to a private room without the repeated movement of a flap. That makes it useful behind a closed bathroom or utility door, especially in an apartment where a litter box needs separation from the main living area. Cats can approach an open doorway rather than pushing against a moving panel.
This standard version accommodates cats up to 20 pounds and fits solid or hollow-core interior doors between 1.25 and 1.75 inches thick. Compared with the Meow Manor XL, it has a smaller size limit, while the Gnome Door offers more decorative character. Installation instructions and sturdy screws provide a more substantial fix than adhesive-mounted alternatives.
Standout Benefits
- The flap-free opening keeps passage quiet and direct.
- The design creates privacy around a litter box or feeding area.
- It fits common solid and hollow-core interior doors.
- The screwed installation suits a permanent room division.
Details To Watch
- The 20-pound limit excludes larger adult cats.
- The door thickness range excludes unusually thin or thick panels.
- Its open passage is intended for indoor doors rather than exterior weather exposure.
Who Should Grab It
This Meow Manor suits apartment residents with indoor cats up to 20 pounds who want a private litter or feeding room behind a standard interior door.
Where A Sibling Pick Shines
Purrfect Portal Meow Manor XL No-Flap Interior Door, White is the better fit for larger cats or any home needing a roomier passage.
What Matters Before You Cut a Doorway
Start With The Access System
A microchip-activated flap identifies your cat through its implanted chip, while the PetSafe model uses a magnetic collar key. Neither system is interchangeable. Consider collar comfort, the number of cats entering your home, and whether you need individual recognition rather than basic schedule control.
Measure The Complete Installation
Check the cut-out, overall flap dimensions, and door thickness before choosing. UPVC, metal, wood, glass, and masonry each present different installation conditions. Ferplast Swing 5 also requires its optional tunnel beyond 5 centimetres, while the Cat Mate adapter has a specific 213-by-262-millimetre requirement.
Separate Interior And Exterior Needs
No-flap interior doors are quieter and easier for a cat to navigate, but they do not provide the weather sealing of exterior models. An exterior installation calls for magnetic closure, brush seals, weather resistance, and secure locking. An interior room division mainly needs a clean opening, secure fasteners, and an opening sized for your cat.
Match The Opening To Your Cat
The flap opening, rather than the exterior housing dimensions, determines passage comfort. Small and medium cats fit the Cat Mate 2-Way-Locking Cat Flap, while the Purrfect Portal XL supports cats up to 30 pounds. Measure the narrowest part of the route, not just the flap, so your cat can pass without turning sideways.
What To Check Before Installation
Mistakes Worth Dodging
Do not choose from exterior or interior use alone. Confirm the door material, thickness, cut-out dimensions, and pet size before modifying the panel. A microchip model also needs compatible identification, while an adapter kit works only with its specified flap and door type.
What Separates Premium From Basic
A higher-tier model may add selective entry, stronger weather seals, programmable locking, or a wider opening. The extra capability matters when your cat uses a busy exterior doorway, several animals need individual access, or your pet needs more clearance. A simple interior divider may provide everything your home requires.

What Is a Microchip Cat Door?
A microchip cat door recognizes a cat through its implanted microchip before allowing entry. It provides selective access without requiring a special key collar.
Does Every Cat Door in This List Use a Microchip?
No. Only the Cat Mate Microchip Activated Cat Flap uses microchip identification. The other options use magnetic keys, manual locking, or flap-free interior access.
What Size Cat Door Do I Need?
Choose an opening your cat can pass through comfortably. Small and medium cats suit the Cat Mate 2-Way-Locking model, while larger cats benefit from the Purrfect Portal Meow Manor XL.
Can These Doors Fit Interior Doors?
The Purrfect Portal models are designed for interior doors, with the Meow Manor fitting solid or hollow-core panels from 1.25 to 1.75 inches thick. Exterior models also need suitable weather seals and a compatible installation surface.
Do I Need to Cut a Hole in My Door?
Most cat doors require a cut-out sized to the installation template or stated dimensions. Measure the panel and follow the supplied instructions, especially with glass, UPVC, or metal doors.
Final Thoughts
The right cat door depends on the job it needs to do. Select the Cat Mate Microchip Activated Cat Flap for individual identification, the PetSafe model for collar-key control, or a Cat Mate exterior flap for compact weather sealing. For indoor privacy, the Purrfect Portal options offer a cleaner, flap-free route that suits everyday apartment and home use.
