Last Verified: August 2, 2026
Review Basis: This research-based review is based on current official manufacturer information, verified retailer listings, and publicly available product information as of August 2026. Because TopPetTech has not conducted hands-on testing of these products, our recommendations are based on research and feature comparison rather than personal product testing.
Cat owners love giving their pets some independence, but traditional cat flaps can create problems. They may allow stray cats or wildlife into the home, contribute to heating or cooling loss, and give owners little control over when their cat comes and goes.
Smart and microchip cat doors offer a more controlled alternative. Depending on the model, these doors can recognize an implanted microchip or RFID collar tag, while some smart models also provide app-based controls, activity notifications, or scheduled access. The door unlocks for an authorized pet and then locks again, helping reduce unwanted entry while allowing your cat greater freedom.
For cats that spend time outdoors, a smart door can also be part of a broader safety setup. You may want to explore our guide to Best GPS Trackers for Cats 2026 to help monitor your cat while it is outside. A pet camera positioned near the entrance can also help you see when your cat enters or leaves.

Buying Guide: What to Consider When Choosing a Microchip Cat Door
Microchip vs. RFID Access
A true microchip cat door reads your cat’s implanted identification microchip, eliminating the need for a collar tag. RFID-based doors rely on a compatible collar key or tag. If your cat regularly loses collars or dislikes wearing one, implanted-microchip access may be the more convenient choice.
Smart Features and App Control
Connected models can offer features such as remote locking, access schedules, activity notifications, and entry or exit monitoring. These features can be useful if you spend time away from home, but they may also require Wi-Fi, an app, a hub, or additional setup.
Door Size
Always check the flap opening against your cat’s size before purchasing. This is especially important for large cats. A door with suitable technology is still a poor choice if your cat cannot pass through it comfortably.
Multi-Pet Access
For multi-cat households, check how many pet identities the door can store and whether access can be managed individually. Some advanced models can control which cats are allowed outside while still permitting others to enter.
Installation
Microchip cat doors may be installed in standard doors, walls, or glass depending on the model. Wall and glass installations often require additional adapters or professional installation, so confirm compatibility before purchasing.
Power and Connectivity
Most electronic microchip doors use replaceable batteries, while connected models may also depend on Wi-Fi, a hub, or an optional power adapter. Check battery requirements and what happens if power or connectivity is interrupted.
1. SureFlap Microchip Pet Door—Best Overall for Secure Selective Entry
Why It Stands Out
The SureFlap Microchip Pet Door stands out for combining selective-entry security with the convenience of using your pet’s existing identification microchip. It scans a registered pet’s microchip on entry and unlocks the flap, helping prevent unregistered animals from entering the home. A built-in curfew mode adds another useful layer of control by allowing owners to set automatic lock and unlock times.
Best For
Cat owners who want secure, collar-free selective entry, particularly multi-pet households or homes where stray cats and other unwanted animals are a concern.
Key Specifications
| Specification | Details |
|---|---|
| Access Method | Implanted identification microchip or compatible SureFlap RFID collar tag |
| Pet Capacity | Stores up to 32 pet identities |
| Entry Control | Selective entry for registered pets |
| Curfew Function | Programmable automatic locking and unlocking times |
| Flap Opening | 7.5 in (W) × 6 11/16 in (H) |
| Power Source | 4 C-cell alkaline batteries (not included) |
| Estimated Battery Life | Up to 12 months, depending on use |
| Low-Battery Indicator | Yes |
| Installation Options | Doors, walls, and glass; accessories may be required |
| Suitable For | Cats, larger cats, and small dogs |
| Warranty | 3 years |
Pros
- Uses an existing implanted microchip, so a collar is not required for microchipped pets
- Stores up to 32 pet identities
- Helps prevent unregistered animals from entering
- Built-in curfew scheduling
- Suitable for larger cats as well as small dogs
- Low-battery warning
- Three-year manufacturer warranty
Cons
- Requires four C-cell batteries
- Wall and glass installations may require additional accessories
- Selective microchip scanning controls entry rather than individually restricting normal exit
- Does not provide smartphone monitoring or remote app control
Our Verdict
The SureFlap Microchip Pet Door is a strong choice for households that prioritize reliable selective entry without requiring their cat to wear a collar tag. Its support for multiple registered pets, curfew scheduling, larger opening, and straightforward microchip recognition make it especially practical for multi-cat homes and larger cats. However, owners looking for smartphone notifications, remote locking, or detailed activity monitoring should consider an app-connected model instead.
2. PetSafe SmartDoor Connected — Best App-Controlled Choice
Why It Stands Out
The PetSafe SmartDoor Connected combines selective pet access with remote control through the My PetSafe app. Owners can create individual schedules, receive door-use notifications, and remotely lock or unlock the door. The Medium model can also recognize compatible implanted microchips in cats, providing collar-free access for supported microchips.
Best For
Pet owners who want app-based control, customized access schedules, and notifications when their cat uses the door.
Key Specifications
| Specification | Details |
|---|---|
| Access Method | Pet Door Key; compatible cat microchips on Medium model |
| Smart Control | My PetSafe app |
| Remote Lock/Unlock | Yes |
| Custom Schedules | Yes, including individual pet schedules |
| Notifications | Door use, lock status, battery status and other updates |
| Wi-Fi | 2.4 GHz connection required |
| Medium Flap Opening | 7.1 in (W) × 7.8 in (H) |
| Pet Size — Medium | Up to 25 lb |
| Power — Medium | 4 C-cell alkaline batteries or optional power adapter |
| Weather Protection | Dynamic weather sealing |
| Locking System | Multi-point locking mechanism |
Pros
- Remote locking and unlocking through the app
- Individual access schedules for different pets
- Smartphone notifications
- Medium model supports compatible implanted microchips for cats
- Selective entry and exit
- Weather sealing and multi-point locking
Cons
- Requires Wi-Fi for connected features
- Microchip compatibility is limited to the Medium model and cats
- Power adapter is sold separately
- More complex than a basic microchip-only door
Our Verdict
The PetSafe SmartDoor Connected is a strong choice for owners who want more control than a traditional microchip door provides. Its combination of remote locking, individual schedules, notifications, and selective access makes it particularly useful for connected homes and multi-pet households. For cat owners, the Medium version is the model to consider if implanted-microchip access is important.
3. SureFlap Microchip Cat Door Connect + Hub — Best for Smart Monitoring
Why It Stands Out
The SureFlap Microchip Cat Door Connect combines microchip-controlled access with app-based monitoring and remote control. Its DualScan technology can manage individual exit permissions for different cats, while the Sure Petcare app provides entry and exit notifications, activity information, curfew scheduling, and remote locking.
Best For
Multi-cat households and owners who want microchip access control combined with remote monitoring and individual exit permissions.
Key Specifications
| Specification | Details |
|---|---|
| Access Method | Implanted microchip or compatible SureFlap RFID collar tag |
| Smart Connectivity | Sure Petcare Hub + Sure Petcare app |
| Entry & Exit Control | DualScan technology with individual exit permissions |
| Remote Lock/Unlock | Yes |
| Activity Notifications | Yes |
| Curfew Scheduling | Yes |
| Flap Opening | 5 5/8 in (W) × 4 3/4 in (H) |
| Power Source | 4 AA batteries (not included) |
| Estimated Battery Life | Up to 12 months |
| Installation | Doors, walls, or glass; accessories may be required. |
| Pet Capacity | Up to 32 pet identities |
Pros
- Recognizes implanted microchips
- Individual entry and exit permissions
- Remote locking and curfew scheduling
- Entry and exit notifications
- Useful activity monitoring for multiple cats
- Helps prevent unregistered animals from entering
Cons
- Hub is required for connected app features
- Smaller opening may not suit very large cats
- Additional accessories may be needed for wall or glass installation
Our Verdict
The SureFlap Microchip Cat Door Connect is particularly well suited to multi-cat households that need more control than a basic microchip door provides. Individual exit permissions are its key advantage: one cat can be allowed outdoors while another remains indoors. The app’s remote controls and activity notifications add useful monitoring, although buyers should factor in the Hub requirement.
4. Ferplast SWING MICROCHIP LARGE—Best for Large Cats
Why It Stands Out
The Ferplast SWING MICROCHIP LARGE combines selective microchip entry with a larger opening designed for big cats and small dogs. It stores up to 30 microchip codes and adds practical features such as four-way access control and a Wind Stopper system to help reduce draughts.
Best For
Large cats and multi-pet households that need a roomier microchip-controlled door without app connectivity.
Key Specifications
| Specification | Details |
|---|---|
| Access Method | Implanted microchip or included collar with microchip |
| Microchip Compatibility | ISO 11784, 15-digit microchips |
| Pet Capacity | Stores up to 30 microchip codes |
| Access Settings | Entry only, exit only, entry/exit, fully locked |
| Opening Size | 17 × 20 cm |
| Overall Dimensions | 26.5 × 16.2 × 31.5 cm |
| Suitable For | Large cats and small dogs |
| Draught Protection | Wind Stopper System |
| App/Wi-Fi Control | No |
Pros
- Genuine implanted-microchip recognition
- Larger opening for bigger cats
- Stores up to 30 microchip codes
- Four-way access settings
- Wind Stopper system
- Collar with microchip included for pets without an implanted chip
Cons
- No smartphone app or remote monitoring
- Microchip scanning is for authorized entry rather than individual electronic exit control
- Larger installation footprint than standard cat flaps
Our Verdict
The Ferplast SWING MICROCHIP LARGE is a strong alternative for owners of larger cats that may find standard microchip cat doors restrictive. Its combination of a spacious opening, support for up to 30 microchips, four-way access settings, and draught protection makes it particularly suitable for larger or multi-pet households. Owners wanting remote monitoring or app-based controls should instead consider a connected model.

Safety & Usage Notes
- Follow the manufacturer’s installation instructions, particularly when fitting a cat door into glass or a wall.
- Check the flap dimensions carefully to ensure your cat can pass through comfortably.
- Check battery-powered doors regularly and replace batteries when the low-battery indicator appears.
- For app-connected models, maintain a reliable Wi-Fi connection and keep the manufacturer’s app updated.
- Introduce your cat to the new door gradually rather than forcing it through the flap.
- A microchip cat door can help control access to your home, but it does not protect your cat from outdoor hazards once your pet leaves the property.
Frequently Asked Questions
What is a microchip cat door?
A microchip cat door reads your cat’s implanted identification microchip and unlocks for registered pets. This allows selective entry without requiring your cat to wear a special collar tag.
Can a microchip cat door keep other animals out?
A selective-entry microchip door remains locked to unregistered animals, which can help prevent stray cats and other unwanted animals from entering. However, no pet door should be considered completely wildlife-proof or escape-proof.
What is the difference between a microchip cat door and an RFID cat door?
A microchip cat door can recognize an implanted identification microchip, while an RFID cat door typically requires a compatible tag or key attached to the pet’s collar. Some models support both methods.
Can microchip cat doors control when my cat goes outside?
Some models offer curfew schedules or directional access controls. More advanced connected models may also allow remote locking, individual access schedules, or entry and exit management through an app.
Do smart microchip cat doors require Wi-Fi?
Not all of them. Standard microchip doors can operate without Wi-Fi, while app-connected models generally require additional connectivity such as Wi-Fi and, in some cases, a compatible hub.
Can microchip cat doors be used for multiple cats?
Yes, many models can store multiple pet identities. However, the number of supported pets and whether individual entry or exit permissions can be assigned varies by model.
Final Verdict
The best microchip cat door depends on how much control and connectivity you need. The SureFlap Microchip Pet Door is our best overall choice for secure selective entry, while the PetSafe SmartDoor Connected is better suited to owners who want app-based control and customized access schedules.
For households that want detailed monitoring and individual access management, the SureFlap Microchip Cat Door Connect + Hub offers the strongest connected features. Owners of larger cats should consider the Ferplast SWING MICROCHIP LARGE, which combines microchip recognition with a more spacious opening.
Whichever model you choose, check your cat’s size, microchip compatibility, installation requirements, and access-control needs before purchasing.
