The best microchip cat flap depends on your pet’s chip type, the number of pets that need access, and how much control you want over entry and exit. The SureFlap Microchip Cat Flap is a strong fit for common chip formats and a compact opening; PetSafe suits multi-pet homes; and Cat Mate offers four-way access control. The two remaining products below are not microchip cat flaps, but may suit buyers comparing wall access or microchip-controlled feeding instead.
| Product | Best For | Key Consideration |
|---|---|---|
| SureFlap Microchip Cat Flap | Common chip formats and selective entry | Small flap opening |
| PetSafe Microchip Cat Door | Homes with multiple programmed pets | Reads 15-digit microchips |
| Cat Mate Microchip Cat Flap | Four-way access control | Not compatible with some chip types |
| Ideal Pet Wall Entry Door | Large wall openings | Not microchip activated |
| SureFeed Microchip Feeder | Separating pets at mealtimes | Not a cat flap |
SureFlap Microchip Cat Flap
Best for: Households that want selective entry and need compatibility with several common microchip formats. This flap reads a pet’s implanted ID on entry and can learn up to 32 identities, helping keep unprogrammed animals from entering.
It works with 9-digit Avid Secure, 10-digit FDXA, and 15-digit FDXB microchips. One-button programming is intended to make setup straightforward. The opening measures 4¾ inches high by 5⅝ inches wide, and the product can be installed in a door, window, or wall with appropriate accessories.
Limitation: The opening is relatively compact, so check your cat’s size against the listed dimensions before choosing it. The feature description specifies selective screening on entry, not a four-way lock.
PetSafe Microchip Cat Door
Best for: Multi-pet homes that want to program several animals for access. The door reads a cat’s unique 15-digit microchip ID and can grant access to the selected pet and up to 39 additional programmed pets.
This model is designed to let authorized pets move in and out while helping prevent unwanted animals from entering. For cats without a microchip, programmable collar keys are sold separately. Choose this option if your pets have compatible 15-digit IDs and a larger list of authorized animals is useful.
Limitation: The listed chip compatibility is limited to 15-digit IDs. Check the pet’s microchip format before buying; the supplied product details do not specify a flap opening size or installation options.
Cat Mate Microchip Cat Flap
Best for: Owners who want to control whether pets can go in, go out, or use the flap at all. Its four settings are in and out, in only, out only, and fully locked. It can store access for up to 30 cats and reads compatible microchips or separately sold Cat Mate ID Discs.
The flap is described as suitable for small to medium cats and small dogs. Its brush seals, magnetic closure, and weather-resistant design are useful considerations for an exterior opening. It supports 15-digit ISO and AVID microchips.
Limitation: It is not compatible with 10-digit microchips or chips containing letters. Confirm the chip type before choosing it, particularly if your pet has an older or less common ID.
Ideal Pet Wall Entry Door
Best for: Buyers who need a large wall-mounted pet opening rather than chip-based selective access. This extra-large model has a 9¾-by-17-inch flap and a telescoping tunnel for walls 4¼ to 9¼ inches thick. Its double flexible vinyl flaps are designed to create an insulating air lock.
The package includes hardware, a template, and installation instructions. It may be worth comparing with a microchip flap when opening size or wall installation is a priority.
Limitation: This is not a microchip-activated cat door. Its listed lock-out slide does not provide pet-ID recognition, so it will not selectively admit a chipped cat while blocking other animals.
SureFeed Microchip Pet Feeder
Best for: Multi-pet households that need to keep one animal from eating another’s food. This automatic feeder opens for an assigned pet’s microchip and closes when the pet moves away. It supports 9-digit Avid Secure, 10-digit FDXA, and 15-digit FDXB IDs.
The feeder holds 13.5 fluid ounces of wet or dry food. A neoprene lip helps seal the lid to retain moisture, and selective access can help separate meals, including prescription diets.
Limitation: This is a feeder, not a door. It does not provide indoor or outdoor access, so choose a cat flap instead if your main goal is controlling movement through an entryway.
Buying Guide: How to Choose a Microchip Cat Flap
Which microchip format does your cat have?
Check the chip number with your veterinarian, shelter, or rescue organization before buying. Compatibility differs: SureFlap lists 9-, 10-, and 15-digit formats; PetSafe lists 15-digit IDs; and Cat Mate supports 15-digit ISO and AVID chips but excludes 10-digit chips and chips containing letters. A collar tag may be an option for some models, but confirm the specific product’s instructions.
How many pets need access?
Compare the stated memory capacity with the number of pets you want to authorize. SureFlap supports up to 32 identities, PetSafe up to 40 total programmed pets, and Cat Mate up to 30 cats. These figures describe programmed identities, not a guarantee that every pet’s chip format is supported.
Do you need entry control or control in both directions?
If blocking unrecognized animals from entering is the priority, compare the selective-entry features of the microchip models. If you also want to restrict outgoing movement, Cat Mate specifically lists in-only, out-only, and fully locked settings. Review each model’s stated controls rather than assuming all chip flaps operate the same way.
Will the opening and installation fit?
Measure your pet and compare the measurements with the listed flap opening. Also consider whether you are installing in a door, window, or wall. SureFlap lists multiple installation locations with accessories, while the Ideal Pet wall door is designed for a specified wall thickness but does not read microchips.
Frequently Asked Questions
Can a microchip cat flap keep stray cats out?
A selective-entry flap can restrict entry to programmed pets, which helps prevent unrecognized animals from coming inside. The exact direction and locking controls vary by model.
Do all microchip cat flaps work with every chip?
No. Check the listed chip formats for the specific flap and compare them with your pet’s chip number before purchase.
Can a cat without a microchip use one?
Some models support a separately sold programmable collar tag or ID disc. Confirm which accessory works with the flap you are considering.
Is the Ideal Pet wall door a microchip cat flap?
No. It is a wall-entry pet door with a lock-out slide, but its listed features do not include microchip recognition.
Does the SureFeed product control a cat’s movement?
No. It is a microchip-activated feeder for selective food access, not an entry door.
