Sureflap Microchip Cat Flap Review

Note: If you’re new to microchip cat flaps and are not sure how they work or why you might need one, you can read this article- Microchip Cat Flap Introduction.

So you have decided that you would like to purchase a microchip cat flap, but which one? Luckily there aren’t too many options, in fact there are just two. You may be aware of a ‘cat-fight’ going on between the two companies producing these models, and unfortunately, this has led to a lot of misleading marketing information. This is where this website comes in, as one of the few places you can still get unbiased, knowledgeable and tested information.

The Sureflap Microchip Cat Flap

Our Verdict:

The Sureflap was the first microchip cat flap we bought and were so impressed with it, that we decided to produce this website. To enable us to speak with confidence about all microchip cat flaps, we also bought the competitor model and installed it in our utility door (yes, the neighbours thought we were mad). We’ve had the Sureflap model for about 18 months now, and the competitor for 12. Here’s what we found.

The Sureflap microchip cat flap looks just like any other good-quality pre-existing cat flap and will fit into the standard-sized cat flap hole, which is clearly a big advantage. If you need to fit it to a glass door, then a mounting adapter can be easily purchased with the model.

Power Supply

Sureflap BatteriesThe Sureflap runs from four AA batteries, which are neatly positioned in the top of the model on the ‘inside’ half of it. According to the manufacturer, these will need to be replaced every 12 months, however we have this model and have found that we are replacing the batteries every 6 months, but we have two cats and so maybe that is what caused this discrepancy. You don’t need to worry about the batteries running out and locking your cat out, because there is an easy to read battery life indicator light that keeps you informed of the current power level.

Reliability of the Microchip Reader

We and many other customers have found the Sureflap Microchip Cat Flap to be extremely reliable, and the microchip in our cat has always been read quickly and successfully. One ‘problem’ stated by the competition is that the cat needs to place its head inside or at least close to the tunnel for the microchip to be read, however we don’t feel that this is an issue at all because if your cat wants to come inside then, unless it comes in backwards (surprisingly, we are yet to find this), then its head is going to be inside the tunnel. The competition ‘solved’ this by building a large canopy over the entrance to the flap, which then scans the cat before it enters the tunnel. We feel this design has more to do with their scanner being too bulky to fit inside the tunnel. The porch of the competitor model is also dangerous as we have clattered our shins into it a few times when we have opened the door and are walking outside, we pulled the machine from the door each time we did this and so there is no longer a flush fit with the door.

Other Features

Sureflap Box

The Sureflap Microchip Cat Flap can store the microchip details of up to 32 different cats, so you can never have too many! It also comes with a two-year guarantee, so peace of mind is assured even though in all likelihood you’ll never have to use it.

Sureflap Microchip Cat Flap- Conclusions and Price

The final major plus point with the Sureflap Microchip Cat Flap is the price. It’s about the same price as its competition. Be careful not to overpay, we found a great deal at this shop. Top tip! That shop is MUCH cheaper than the manufacturers website!

    Thank you for your extremely helpful website. I am looking to replace my Petporte catflap that has broken. The microchip in one of my cats has migrated from his neck to half way down his back. He can get in using the Petporte, do you have any idea whether this might be a problem with the Sureflap?
    Many thanks.

      Hello Susie, what a pain! Unfortunately I haven’t got any experience of this problem. Obviously your cat’s microchip won’t be directly under the Sureflap reader, but I imagine there is some sort ‘range’ within which the reader will pick up the microchip. If this wasn’t the case then you’d expect cats to have more trouble getting the door to open straight away. Only thing is I don’t know what that ‘range’ could be! Have you tried contacting the manufacturer? I think this could be a topic for a future post! Thanks for getting in touch.
