A microchip cat flap reads the chip your cat already has, so only your cats get in. It stops intruder cats eating your cat's food, and a curfew can keep your cat in at night. Your cat's microchip is a legal requirement in England anyway, so there is nothing extra to wear.

SureFlap is the name most UK vets and cat owners know, and this is the flap that made it popular. It learns your cat's microchip in seconds, keeps intruders out, and runs for around a year on four AA batteries.
The Connect version adds the Sure Petcare app. You can see when your cat leaves and comes home, lock the flap from your phone, and set a curfew that changes automatically. It works with the same Hub as the SureFeed microchip feeder.
Cat Mate is a long-standing UK brand, and its microchip flap does the core job of keeping other cats out for less money than SureFlap.
The Petporte has a built-in curfew timer and comes with a mains lead, so you can keep your cat in at night without an app or hub. It's a good middle ground between a basic flap and a fully connected one.
Check the flap's tunnel size against your cat, especially big breeds like Maine Coons. Also check whether you need a kit for glass, brick or metal doors.
Many owners keep cats in at night for their safety. A timer flap or an app-connected flap does it automatically.
The flap reads the chip, but a found cat is only returned if the chip details are current. Check the database record when you set up the flap.
Most read all the common pet microchip types used in the UK. If your cat has an older or unusual chip, the manufacturers sell RFID collar tags as a backup.
Yes, but you'll need a glazier to cut the hole and usually an adaptor kit for the flap. Many glaziers can supply the glass with the hole already cut.
In England, cats must be microchipped by the time they are 20 weeks old, and owners must keep their details up to date on a database.
