But which one truly delivers the convenience, security, and smart features you need?

Buying Guide

Selective Entry & Pet Recognition

Both SureFlap models use RFID to read your pet’s implanted microchip, ensuring only authorized animals enter. The SureFlap Microchip Cat Flap and Pet Door learn up to 32 identities, while the PetSafe SmartDoor also supports chip reading plus a separate key tag. The PetSafe app lets you manage permissions per pet, creating individual schedules and lock times. For households with multiple pets, this flexibility is a major advantage. If you have a cat that hates wearing a collar, the microchip-only SureFlap is ideal. But for dogs, the PetSafe’s ability to use either chip or key tag gives you options.

App Control & Smart Features

The PetSafe SmartDoor is the clear winner for remote control. Through the My PetSafe app, you can lock or unlock the door from anywhere, receive notifications when your pet goes in or out, and set custom schedules. The SureFlap does not offer app connectivity, focusing instead on a simple one-button programming system and battery operation. If you often travel or want to monitor your pet’s comings and goings, the PetSafe SmartDoor is the modern choice. However, if you prefer a straightforward, no-app solution, the SureFlap is reliable and easy to use. For more on smart pet products, visit our Pet Tech Guides.

Installation & Compatibility

All three doors can be installed in doors, walls, or windows with the right accessories. The SureFlap Microchip Cat Flap has a smaller opening (4 3/4″ H x 5 5/8″ W) suited for cats, while the PetSafe SmartDoor (medium) and the SureFlap Pet Door (brown) offer a larger flap for small dogs. Check your pet’s size and the thickness of your door before buying. The SureFlap units run on AA or C batteries (not included) with up to 12 months of life, whereas the PetSafe SmartDoor requires a Wi-Fi connection and a power source near the door. Battery life and smart home integration are key factors to weigh.

Security & Durability

The PetSafe SmartDoor boasts a dynamic weather seal and a multi-point locking mechanism, making it both energy-efficient and secure against intruders. The SureFlap doors offer selective entry but rely on a simpler flap design. For homes in harsh climates or with persistent wildlife issues, the PetSafe’s sealing and remote lock are strong selling points. However, the SureFlap doors are built to last, with a three-year warranty and proven reliability. Read more about comparing pet tech in our overview of pet door options.

Final Thoughts

Both brands offer excellent solutions, but your decision comes down to smart features versus simplicity. If you want remote control, scheduling, and phone notifications, the PetSafe SmartDoor Connected Pet Door is the clear winner. For a reliable, battery-powered, microchip-only door that works seamlessly for cats, the SureFlap Microchip Cat Flap provides great value and long-lasting performance. Pick the one that best matches your lifestyle and pet’s needs.
