The best microchip cat flap is the one that fixes your access problem without forcing your cat to carry another key. Within Sure Petcare, the Microchip Cat Flap Connect is aimed at cats and lets you manage permissions and activity via a Hub/app; the Microchip Pet Door Connect offers a larger opening for big cats and small dogs, with remote control and scheduling. The important difference is that not every door handles entry and exit in the same way. Before you buy, measure your animal, check door/wall thickness and confirm whether you need to block intruders, control exits, or both.
Italy/EU: Sure Petcare sells European versions, but mounting accessories, adapters, the Hub and stock vary. On Amazon Italy check exactly which parts are included in the package.
Microchip doesn’t automatically mean full two-way control
A common mistake is reading 'microchip' and assuming the flap will decide for both directions for every animal. Models can behave differently.
The SureFlap Microchip Cat Flap Connect is built around per-animal permissions and connected features. The Microchip Pet Door Connect, with its larger opening, lets you control access and schedules from the app, but Sure Petcare specifies how entry/exit selectivity works on that model.
Action: write your problem in one sentence: 'I want my cats in but not the neighbor', 'I want one allowed out and another not', or 'I want to lock overnight'. Then check that the exact model solves THAT access direction.
Cat Flap Connect vs Pet Door Connect: first, measure your cat

| Criteria | Microchip Cat Flap Connect | Microchip Pet Door Connect |
|---|---|---|
| Target user | Cats | Large cats and small dogs |
| Identification | Microchip compatible / collar tag compatible | Microchip compatible |
| App | Yes, via the Connect/Hub ecosystem | Yes, remote control and schedules |
| Key use | Manage individual access and activity | Larger opening and connected control |
| Installation | Door, wall or glass with the right accessories | Depends on surface and adapters |
Purchases fail more because of installation than electronics. An opening that's too small forces the cat to brush or crouch; a huge opening can be unnecessary and complicate fitting.
The vet-implanted microchip can be the key, but check compatibility
Sure Petcare works with compatible microchips and offers collar tags as an alternative in some cases. The mistake is buying first and checking later whether your pet's chip reads properly.

Action: confirm the supported standard/compatibility listed on the official spec and set up the door while you still have the return window. If the chip is badly positioned, old or not readable, ask your vet to verify it.
Hub and app: decide if you really need the Connect version
A basic microchip flap without online connectivity can already keep unauthorized animals out. The Connect version adds telemetry and remote control. The mistake is paying for connectivity when you only need a selective flap.
The app makes sense if you want notifications, activity logs, mobile scheduling or to change rules without being by the door. If those features are unnecessary, compare standard SureFlap models without online connectivity too.
Buy the function, not the word 'smart'. Microchip solves identity; Connect solves remote control and logging.
Installation in glass, wall or door: this is where hidden costs can appear

The mistake is budgeting only for the flap. Glass, thick walls or metal doors can require adapters, tunnels or professional installation.
Before buying, check the official cut templates and accessories. With double glazing you usually don't improvise a hole after manufacture: consult a glazier before ordering the piece.

Action: add product + Hub if applicable + adapter + tunnel + installation. That's the real purchase price.
Night schedules: useful, but they don’t replace watching your cat’s routine
Blocking exits at certain hours can be practical in urban areas or during routine changes. But a sudden change can frustrate a cat used to going out.
Introduce restrictions gradually where possible and make sure the pet has a litter tray, water, hiding spots and indoor enrichment. Technology controls the door; it won't solve indoor enrichment by itself.
Decision matrix
| Need | What to buy/check |
|---|---|
| Keep other cats out | Microchip-reading flap that limits entry |
| Large cat | Measure first and compare Pet Door Connect |
| Control from mobile | Connect version + Hub required |
| Only chip selection | Also compare standard SureFlap options without Connect |
| Installation in glass/wall | Budget for adapter and pro work before cutting |
Checklist before buying on Amazon Italy
- Measure your cat: shoulder width and comfortable height.
- Measure the surface: thickness and material.
- Check the chip: compatibility and readability.
- Confirm Hub: included or sold separately.
- Define direction: which animal may enter and who may exit.
- Accessories: correct tunnels/adapters.
- Adaptation plan: teach the flap before depending on it.
Frequently asked questions
Do I need to put a collar on my cat?
If the implanted microchip is compatible and reads well, the main advantage is using it as the identifier. Collar tags are an alternative in specific situations.
Will the flap work if the Internet goes down?
Local rules and exact behavior depend on the model. Connectivity adds app features and remote control; check the manual to see which permissions remain stored and test the operation before relying on it.
Can I install it myself?
On a simple door it can be viable following the template. Glass, metal or thick walls may require accessories and a professional. Cutting a surface badly usually costs more than a correct installation.
Verifiable sources
The door can decide who enters the house; if the problem happens later, when one cat steals the other's food, you need to apply the same identity logic to the bowl.
