Our #1 Pick: SureFlap Microchip Cat Flap
by Sure Petcare
SureFlap Microchip Cat Flap
Uses your cat's existing microchip to keep intruder animals out. Compatible with all common microchip types.
Why These Products Matter
Security & Safety
Microchip and smart flaps keep intruder cats, foxes, and wildlife out of your home while giving your cat unrestricted freedom.
Independence for Your Cat
No more getting up at 5am to let the cat out. Your cat comes and goes as they please, reducing stress for both of you.
Energy Efficiency
Modern cat flaps feature draught excluders, brush seals, and double-flap designs to minimise heat loss through the opening.
Health Monitoring
Smart connected flaps track how often your cat goes in and out, alerting you to changes in behaviour that could indicate illness.
Buying Guide
When choosing a cat flap, consider four key factors: security level (microchip > magnetic > manual), your cat's size (measure shoulder width and height, add 2-3cm), installation surface (wood, glass, brick, or uPVC), and budget. Microchip flaps are the gold standard — they read your cat's implanted chip and keep strays out without needing a collar. Smart flaps add app control, curfew timers, and activity tracking. For multi-cat homes, look for models that store 20+ microchip IDs and offer individual access settings per cat.

How to choose the best microchip cat flap
1. Measure your cat first
Measure shoulder width and add 2–3cm clearance. Standard SureFlap and PetSafe models suit cats up to about 6kg. For Maine Coons, Ragdolls or British Shorthairs over 6kg, choose the SureFlap Microchip Pet Door with its larger 178 × 170mm opening.
2. Match the flap to the surface
Wooden and uPVC doors take any standard flap with a jigsaw cut. Glass needs a professional glazier and a Cat Mate Glass 210 or SureFlap glass adaptor. Brick walls thicker than 100mm need a tunnel extension and usually a builder.
3. Decide if you need app control
Standalone microchip flaps are simpler and cheaper. A smart flap like the Sure Petcare Connect adds scheduled curfews per cat, activity logs and remote lock/unlock from your phone — useful if you work shifts or travel often.
Microchip Cat Flap FAQ
Cat Flap Buying Guide
Everything you need to know before you buy
Microchip Cat Flaps
These read your cat's implanted microchip to allow entry, keeping strays and wildlife out. No collar needed. The gold standard for multi-cat households.
Magnetic Cat Flaps
Your cat wears a small magnetic tag on their collar. The flap unlocks when it detects the magnet. Affordable but less secure — any magnet can open it.
Manual Cat Flaps
Simple push-open doors with 2-way or 4-way locking. The cheapest option but no selective access — any cat or animal can enter.
Smart Cat Flaps
App-controlled flaps that track your cat's activity, set curfews via your phone, and send notifications. Premium price but ultimate convenience.
Choosing the Right Size
Measure your cat's width and height at the shoulders. Add 2–3 cm for comfort. Most standard flaps fit cats up to 7 kg. For larger cats (Maine Coons, British Shorthairs), look for 'large cat' or 'pet door' models.
Installation Tips
Most cat flaps come with a cutting template. You'll need a jigsaw for wooden doors. For glass or brick, hire a professional. Wall installations usually need a tunnel extension — check the product includes one.
Microchip vs Magnetic vs Manual
If strays are a problem, go microchip. If budget is tight and you're in a safe area, manual is fine. Magnetic is a middle ground but requires a collar. Smart flaps are best for tech-savvy multi-pet households.
