How to Choose the Right Microchip Cat Flaps
- Uses the existing microchip: the best flaps read your cat’s own vet microchip — no new collar tag needed.
- Curfew & timer: if you want cats in at night, choose a timer (Cat Mate Elite) or app model (SureFlap Connect).
- Number of pets: check the stored-pet limit if you have several cats — most hold 30+.
- Fitting surface: confirm it suits your door, wall or glass; glass usually needs an adaptor.
- Opening size: large cats or small dogs need a bigger door like the SureFlap Pet Door.
- App logging: in/out tracking is invaluable for monitoring elderly or unwell cats.
Frequently Asked Questions
Do microchip cat flaps use my cat’s existing chip?
Yes — the models we recommend read the standard microchip your vet already implanted. If your cat isn’t chipped, most also work with an included RFID collar tag.
Will a microchip cat flap keep foxes and other cats out?
Yes. The flap stays locked and only opens for your registered pets, so neighbourhood cats and foxes can’t get in to steal food or spray.
Can I set a curfew to keep my cat in at night?
Yes. Choose the Cat Mate Elite for a built-in timer, or the SureFlap Connect for app-based curfews and remote locking.
Are microchip cat flaps hard to fit?
Most fit standard doors easily with the supplied template. Fitting into glass or a wall is possible but usually needs an adaptor or a professional.
