Buying Guide

Microchip vs. Collar Tag Compatibility

All SureFlap models read your cat’s implanted microchip, which works with 9-, 10-, and 15-digit chip numbers. If your cat does not have a microchip, you can buy RFID collar tags separately. This flexibility ensures every cat can use the door, regardless of whether they are chipped or not.

For homes with multiple cats, the ability to store up to 32 identities is a huge plus. You can program the door to recognize each pet individually, keeping out any animal not on the list. For more on choosing the right door for your exterior, see our guide on best cat doors for exterior doors.

Entry and Exit Control

Basic models scan only on entry, meaning any cat can exit freely. The DualScan and Connect models add exit scanning, allowing you to set permissions for each cat. This is ideal if you want to keep a specific cat indoors at night or prevent an escape artist from leaving.

If you need a door for an exterior wall, the best cat door for exterior wall guide can help you pick the right model for your installation.

Installation Options

SureFlap doors can be installed in doors, windows, or walls. For glass installations, you will need a mounting adapter. The SureFlap Microchip Cat Flap Mounting Adaptor and the Sure Petcare Mounting Adapter are designed to fit the standard cat flap size, making installation in glass panes clean and secure.

For sliding glass doors, you may need additional accessories. Check out our best cat door for sliding glass door recommendations for more options.

Smart Features and Connectivity

The Connect models add Wi-Fi connectivity via the SureFlap Hub, letting you lock or unlock the door remotely and monitor your cat’s comings and goings through the Sure Petcare app. This is a game-changer for pet owners who travel or want to keep an eye on their cat’s activity patterns. The standard models are battery-powered and last up to 12 months, while the Connect models require the hub for smart features.
