You have a cat who loves the outdoors, but you are tired of local strays helping themselves to your home. Or maybe you need a way to keep your indoor cat safe while still letting them enjoy a sunny porch. This is where a microchip or RFID pet door can make all the difference. In this guide, we break down the differences between SureFlap microchip cat doors and standard RFID pet doors, focusing on security, ease of use, and what each model offers. Whether you have a single cat or a multi-pet household, we help you choose the right solution. For more product comparisons, check out our Comparisons category.

Buying Guide
Microchip vs RFID Collar Tags
The primary difference between a microchip pet door and a generic RFID door is how your cat is identified. SureFlap doors read your cat’s existing implanted microchip, so no extra tag is needed. If your cat does not have a microchip, you can use the SureFlap Sure Petcare SureFeed Pack of Two RFID Collar Tags, which are lightweight and easily programmed. This flexibility makes SureFlap models ideal for both microchipped and non-microchipped pets.
Generic RFID doors often rely solely on collar tags, which can be lost or removed. SureFlap’s dual approach ensures your cat always has access, even without a collar. This is a major advantage for owners who worry about tag loss.
DualScan vs Single Entry
If you have multiple cats or want to keep a specific pet indoors at certain times, the SureFlap DualScan Microchip Cat Door is worth considering. It uses dual-scan technology to read the microchip on both entry and exit, allowing you to set permissions per cat. For example, you can keep a young kitten inside while letting an older cat roam. The standard SureFlap Microchip Cat Flap only scans on entry, so it cannot restrict exit.
For most households with a single cat, the single-scan model is sufficient. But if you need that extra control, the DualScan is a smart upgrade.
Installation and Size
All SureFlap doors can be installed in doors, windows, or walls using available accessories. The standard cat flap opening is 4 3/4 inches high by 5 5/8 inches wide, suitable for most cats. The SureFlap Microchip Pet Door (Brown) has a larger opening of 6 11/16 by 7 inches, making it a better fit for small dog breeds or larger cats.
Measure your pet’s height and shoulder width before buying. If you own a thick-coated Maine Coon, the larger flap may be more comfortable. For standard domestic cats, the smaller flap works fine.
Battery Life and Reliability
SureFlap doors run on batteries (4 AA or 4 C, depending on model) and can last up to 12 months under normal use. A low-battery indicator flashes red when it is time to replace them. We recommend using non-rechargeable alkaline batteries for best performance. Compared to generic RFID doors, SureFlap models are known for consistent operation even in cold weather, thanks to their sealed electronics.
If you live in a region with extreme winters, the SureFlap’s robust design is a reliable choice. For more pet tech advice, visit our Pet Tech Guides.
Final Thoughts
Choosing between SureFlap models comes down to your pet’s size and your need for access control. For most cat owners, the SureFlap – Sure Petcare Microchip Cat Flap, White offers excellent value with reliable microchip reading and a simple one-button setup. If you have multiple pets or want to restrict exit for a young or sick cat, the SureFlap DualScan Microchip Cat Door gives you that extra layer of control. Both models keep unwanted animals out while giving your feline friend the freedom they deserve.
Frequently Asked Questions
Can I use a SureFlap microchip door if my cat does not have a microchip?
Yes. You can pair the door with the SureFlap RFID collar tags (sold separately). The door will read the tag instead of an implanted chip. This makes it accessible for all cats.
Does the DualScan model allow me to keep my cat inside at night?
Absolutely. Using the dual-scan technology, you can set separate exit permissions for each cat. For example, you can program the door to keep a specific cat inside after dark while allowing another cat to come and go.
How long do the batteries last in a SureFlap cat door?
With normal use, the 4 AA batteries last up to 12 months. The door has a low-battery indicator that flashes red, giving you plenty of warning before they die. Always use non-rechargeable alkaline batteries for best performance.
Can I install a SureFlap cat door in a wall?
Yes. SureFlap offers wall installation kits (sold separately) for both the standard cat flap and the larger pet door. The installation process is straightforward, but we recommend checking the wall thickness and following the supplied instructions. For more guidance, explore our Comparisons category for setup tips.
