SureFlap Microchip Cat Flap

TLDR Review: SureFlap Cat Flap

Published: January 23rd, 2026

Pros

  • Effectively restricts access to only microchipped cats, keeping out unwanted intruders and bully cats.
  • Programming with the cat’s microchip is straightforward and reliable.
  • Unlike collactivated doors, the microchip system can’t be lost or removed, making it more secure and hassle-free.
  • Battery life generally lasts several months, maintaining near full strength without frequent replacements.
  • Welade with thick plastic and a draught excluder that helps reduce cold air drafts.
  • Easy to install in various door types and interior walls with minimal adjustments.
  • Cat flap unlocks and locks quickly, minimizing unauthorized entry chances.
  • Fits medium to large cats comfortably, though the door opening is slightly narrower than some others.
  • Provides a peaceful, secure solution for multat households with intruder problems.
  • Attractive design and sturdy construction that feels like a premium product.

Cons

  • Some cats show initial hesitation, especially entering back inside, often due to a reflective surface causing confusion.
  • The door reacts slightly slower if a cat rushes through, which may require the cat to be more cautious.
  • Not 100% foolproof; a chasing cat may sometimes sneak in before the door closes fully.
  • Uses a fair amount of battery power in some cases, with reports of needing replacements more frequently than expected.
  • Lacks longer tube extensions, which would benefit installations in wider or thicker walls.
  • Chip recognition controls entry only; exit remains unrestricted, which might be a drawback for some users.
  • Door opening is a bit narrow for very large cats, potentially limiting accessibility for some breeds.
  • The advanced microchip system may be unnecessary if there’s no issue with stray or bully cats, making simpler and cheaper collactivated models a viable alternative.
  • Screw holes might require minor modifications to fit some PVC doors properly.
  • Despite draft reduction, some users still notice a slight breeze through the flap.

Bottom Line

The SureFlap Microchip Cat Flap offers a high level of security and convenience if you’re dealing with multiple cats or unwanted feline visitors, thanks to its reliable microchip recognition and sturdy build. It’s perfect for cat owners who want to avoid collars and want their pets to come and go freely without worrying about uninvited cats sneaking in. However, if you don’t face intruder cats or multi-cat conflicts, this flap’s advanced features and higher price tag ($139.99) might be overkill compared to simpler models. Also, consider your cat’s temperament and wall thickness before buying, especially since some cats take time to adjust and wider walls might need extensions. If you want similar benefits but think your cats might struggle with the door speed or narrow opening, keep an eye out for future models with longer tubes or faster sensors.
