The full review

Microchip Reading

SureFlap stores up to 32 microchip numbers. The pet approaches, the RFID reader in the flap edge reads the microchip within 0.5 seconds, and the door unlocks. Works with all standard 9-digit microchips used in the UK, EU, and US. Registration is a simple one-time scan of each pet.

Multi-Pet Household Use

Program only the cats who should have outdoor access. Dogs, indoor-only cats, or multiple cats with different outdoor privileges can be managed by programming individual microchip access. The curfew mode locks the flap in-only or out-only on a timer — keeping cats inside at night when wildlife predation risk is highest.

Quick verdict

What we love

✓Works with existing implanted microchip — no collar required
✓Selective access for multi-pet households
✓Curfew mode to keep cats in at night

Heads up

✕Installation requires door or wall cutting if not already flap-equipped
✕Battery-operated — 4 AA batteries last approximately 6-12 months

✓ Buy it if…

Multi-pet households where selective access is needed, or any cat owner dealing with uninvited animal visitors.

✕ Skip it if…

Indoor-only cats who never use a cat flap — the technology has no application for cats who don't go outside.

Tucker's bottom line

The most intelligent cat flap available. If your cats have microchips (all should), this is the automatic upgrade.

Common questions

Do I need to reprogram it when I get a new cat?

Simply present the new cat to the reader and trigger a new registration. The unit stores up to 32 chips.

Can it be installed in glass?

Not directly — a tunnel adapter kit allows installation through thick walls. Glass installation requires professional glazier work.
