Product description

Battery-powered microchip cat flap; just press one button to register your cat's chip number, for up to 32 pet identities, also works with a collar tag. Entrance approx. 14 x 12 cm (W x H)
SureFlap MicroChip Cat Flap from Sure Petcare (alternatively the SureFlap Microchip Pet Door for larger cats) is a revolutionary, battery-powered cat flap which reads your cat's existing identification microchip, only unlocking for them. With just a push of the button, the SureFlap cat flap saves your cat's chip number. Up to 32 microchip numbers can be stored in the device memory, so it is perfect for multi-pet homes. If your cat is not microchipped, the cat flap can be activated with an RFID collar tag. The door opens and shuts automatically as your cat goes through the flap. The SureFlap cat flap from Sure Petcare also has an easy-to-use manual 4-way lock, so you can control which direction the flap opens.

Insights from real Pet Parents

AI generated summary based on reviews added by customers

The cat flap is a fantastic addition for providing cats with freedom and security. Installation is straightforward, especially if replacing an existing flap. Some users noted challenges syncing the chip and flap, and suggested a thicker draught excluder. Training might take time due to the unlocking noise, but it effectively keeps other animals out. Users recommend lithium batteries for winter. Overall, it’s a valuable purchase for ensuring controlled access and comfort for cats.

Easy to install.
Prevents other animals from entering.
Provides daytime freedom for cats.
Challenges in syncing the chip with the flap.
Draught excluder could be thicker.

Chip not Responding

Bought March 11th 2025 My Cat was chipped on 7th March 2025.. Easy to install as I already had an original Cat Flap so my cat is familiar. However, I cannot seem to coordinate the cats chip with the flap.Draught excluder is very fine and could do with being thicker as lots of cold air coming through.

Not water proof

Water seeps into the gaps and leaks out a small hole at bottom of flap. In heavy weather you will get large puddles of water developing. When contacting support they say the hole is there to prevent electronics getting wet and to place a towel down. The amount of water is significant. This is definitely a design flaw. I don't not recommend you buy if exposed to rain.

Cat loves it

This was pretty straightforward to install in my wooden door, with some basic DIY skills. It had to be quite low to ground as the door had windows, so cat has to crawl through rather than walk. My cat took a few days to work it all out but clearly loves the freedom it gives him now. He's in and out when I'm not there and at night. I'm using it on manual mode - no batteries & taped down the little tab - I'll wait and see if microchip needed.

Works flawlessly all the time.

I bought the Sureflap for my cat about a year ago. It is an excellent product. It comes with a small internet-connected hub which connects both to the Flap and your phone. Your pet's microchip opens the flap. You can control opening and closing times, ie. keep indoors all night, while still allowing your cat to come back home at any time (curfew setting). It gives a record of each time your pet came in or out. This product changed our lives and I couldn't recommended it highly enough.

Super Product

Purchased this product and it arrived within days. Installed it and it took a few tries for the cat to get used to it and on day 3 of teaching her she is happy using it now. It took a little while to get her used to the click but the timing of the click is perfect and it opens for just enough time for her to get through. I had issues with other cats coming in through the window we had left open for our cat so this is the best solution out there. Would highly recommend Zooplus too.

Excellent!

Installed on garden shed so my outdoor cat could get access to an automatic feeder and kennel inside the shed. Took a few weeks to train him as he was jumpy with the clicking noise when it unlocked, however he uses it very happily now. It’s great at preventing the neighbourhood cats getting into the shed despite their best attempts! Recommend lithium batteries for the winter months to prevent battery drainage in cold weather.

Perfect

Within a few days, both adolescent cats who had never used a cat flap before were in and out like pros. Seems quite sturdy. Easy to fit in a wooden door. Very happy.

Very good

Easy to instal, works as described. Our relatively small cats didn’t take long to learn to use it. It does click so if you have a cat who objects to snappy / clicking noises it might be an issue, but ours will sit next to us while we use power tools so it was no problem for them. Best of all, the big bad bully cat who kept coming in and terrorising ours is now kept out. Highly recommended.

I'm gutted, even though it's a great product

Unfortunately, like only 1 other reviewer, this product seems to be ineffective for my situation. Bought 2 and the greedy cat took to it immediately, but the one who likes to graze won't go near it. He doesn't want to put his head under the arch, and the motor sound terrifies him. Alas, I was so excited for this and feel really sad. Otherwise it's a great product.

Be careful if you have very large cats

I have used these for about 6 years, have 4 cats & 3 feeders, they are all on different diets. One will eat nothing but biscuits - sadly. One on a renal diet, one on a normal elderly diet & have just rescued a skip diver, counter surfer dustbin cat. My Maine coon cannot use his properly. He has a very long neck & because his microchip is between his shoulder blades, it won't recognise it until his head is out the other side of the arch. It then opens & he panics running off with it around his neck. I could use the rfd tag, but, he has never had a collar & feeding him on the hall windowsill at the top of the stairs that only he can reach, seemed an easier option. They are rather large & tricky to clean, especially if your cat eats like a rotavator! Very good item that does save you money as less waste from spoiled food.

A pushy cat can push door over the lock dial

A good flap in many ways, suitable for most cats. However, the dial at the lower left only just covers/blocks the door at lower edge and a pushy cat, even if not that big (mine was 4.5kg) can ram the flap open even when locked. This was just one out of 5 cats, but once he figured this out he popped the door so often by shoving it when locked, that he cracked it.

At last!

I didn’t think my daft cat was going to get it but after almost 6 weeks he’s had a eureka moment and ‘by Jove he’s got it’! We have one cat on a special diet so now he’s learned which bowl is his and all going well. Great idea just give it time and they will get it eventually. Only one design flaw is when on trainer mode the light constantly flashes draining the battery and as with our stupid cat got through lots during that phase.

VIP entrance!

With the price of this product I wanted to give it 6 months before reviewing.This has been such a great purchase!! It gives the cats their daytime freedom and they enjoy going through the the tunnel.I am happy as I know that nothing else can come in the house without the chip opening the door and the draft excluder on it is perfect at keeping the cold out. I've used 3 tunnel add ons for this on my back house wall and it's fine.The click people speak of is not an issue for my two cats (3yrs old)

Excellent product

Reiterating other reviews, this is a brilliant little cat flap. Mickey is a bit of a chubster, but still manages to get in & out easily. He was initially wary of the clicking noise as it unlocks, but has since realised what it is & isn’t bothered. I find it is sensitive, & can hear it clicking the minute his head is anywhere near the flap. It’s less draughty than the manual one & has various settings, so the negative reviews on that are misleading. I have a much calmer cat & no more intruders!

You can teach and old cat new tricks!

When we had a few nights of 'Le Fluffster' coming in at 3am I was imagining all kinds of hazzards befalling him while waiting up - we decided a cat flap was the only way forward! It was easy and simple to install and 1 push of a button registered his chip. He took to it in less than a week. Yes the clunk of the lock is quite loud but it's not taken him long to get used to it. I only wish we'd gone for the 'Connect' version as we'd like to know if he's coming or going.

Excellent product

Used to have a bully of a tom cat so never had a problem with intruders so an ordinary cat flap was fine. That all changed after his sad demise - I now have two very nervy females who were terrorised by other cats coming into the house. This flap allows my cats to come & go but they can rest easy knowing they are now safe when indoors. Very easy to set up and cats soon get used to the click as they come through the flap. Wonderful item.

Money well spent!

I am delighted with this product. The local bully-cat used to chase my gentle little cat in through the ordinary cat flap and beat her up her in her own home. Since I bought SureFlap cat flap only my cat can come in and so she’s safe now.

Good cat keys :-)

It's the first flap for my cat and it seems that he liked it. At first he wasn't sure what to do but he got used it if within a few days. It's big enough for bigger cats (mine has 5 kg) and well made. Setting up and chip learning is a piece of cake. It needs 4 'C type' batteries to work (not included). The noise it makes when opening/closing is quite loud so may frighten some cats at the beginning. I would recommend it, but I have it just for two weeks.

Very good

Firstly in reply to the previous 2 (misleading) comments: 1 - There is a ;ow battery warning light clearly visible on the inside top right of the housing. 2 - You can revert to manual (Non-microchip) mode easily by following the simple instructions in the booklet provided. Does what I wanted it to do - keeps out the neighbours unfriendly cat and allows my 2 cats access. Simple to fit and simple to set up.
