Give your kitty a safe way to get inside while keeping unwanted guests out with the SureFlap Microchip Cat Door. Just like giving your cat their own house key, this flap door is smart enough to know who’s allowed in and who’s not. It works by picking up on your cat’s unique microchip or collar tag, and only opens to let your kitty in, while staying closed for all other animals. Simply program in your cat’s microchip with just one button―you can store up to 32 cats in the system―and install on any door, window or wall. It has no cumbersome cables, and features a manual 4-way lock that lets you control when your cat comes and goes, even a setting to keep him inside at night. The system is compatible with all microchips and RFID collar tags.

  • Flap door knows your cat’s unique microchip or collar tag id and only opens for your kitty.

My pet isn't microchipped, can it use Sure Petcare microchip products?

We recommend you use Sure Petcare products in conjunction with your pet's implanted microchip so that they don't need to wear a collar. However, Sure Petcare products can be used with a Sure Petcare RFID Collar Tag that is unique if your pet is not microchipped.

The Micorchip Pet Door, the Microchip Pet Door Connect and the Microchip Pet Feeder come with one collar tag supplied.

Collar tags are not supplied with the Microchip Cat Flap and the DualScan Microchip Cat Flap and can be purchased separately.

Where can I find the serial number of my Sure Petcare product?

The serial number of the SureFlap Microchip Cat Flap and the SureFlap DualScan Microchip Cat Flap can be found on the underside of the battery compartment lid.

The serial number of the SureFlap Microchip Pet Door and Microchip Pet Door Connect can be found on the underside of the button compartment lid.

The serial number of the SureFeed products (Microchip Pet Feeder & Sealed Pet Bowl) can be found on the underside of the product.

What kind of batteries do you recommend using with Sure Petcare products?

The SureFlap Microchip Cat Flap and the DualScan Microchip Cat Flap operate using 4 AA (1.5V) batteries.

The SureFlap Microchip Pet Door, SureFeed Microchip Pet Feeder & SureFeed Sealed Pet Bowl operate using 4 C cell (1.5V) batteries.

We recommend the use of good quality, alkaline batteries in order to give the longest lifetime. We do not recommend the use of rechargeable batteries with Sure Petcare products.

How long will the batteries last in my SureFeed product?

The batteries on your SureFeed product should last a minimum of 6 months with normal use. This battery life is expected when using good quality, non-rechargeable, alkaline batteries.


3-Year Limited Warranty.

    Bad design, lock does not properly work

    By on

    The system is not reliable enough. After a few weeks, our cat can open the door from inside when the lock is on. He just pulls the door by the side; the lock is not tall enough and the door is too flexible, it takes him a few seconds. And besides, the door remains opened afterwards, letting any other animal come in! Also, keep in mind this cat door cannot be fixed on an exterior wall without buying another accessorial (unlike all our previous cat doors).

    Great product, but...

    By on

    Our cat is starting to get used to it. It certainly gives her more freedom and independence. We would have liked it even more if she didn't start bringing her "trophies" into our house.

    Works as advertised

    By on

    This was very simple to set up and install. A great idea, we're trying to keep cat A out of a litter box so cat B will use it. We installed on an interior closet door. Now, if we could only get her to use it!!! Cats.

    Good BUT...

    By on

    This cat door is great in theory. It took my cat a few days before he figured out how to push through, but I kept getting woken up at night to him smashing himself against it trying to get inside. I think his microchip is too far back on his shoulder to open it, so just ordered the tags. Hopefully that will be a better solution!
