This cat flap is a game changer, technology at its best

This cat flap is a game changer. The technology is used in an intelligent way to simplify our life!
No more hunt of mouse during the night, no more dead parts of animals inside the house. I finally can sleep relaxed.
It works properly, has been smartly designed. The team is working hard to provide new features on the app and support the people for every question!
Worth every penny !

Peace restored!

Peace restored!
My husband was able to easily installed this flap in our existing flap space. Ever since then it has worked perfectly. Watching the videos of my cat trying to bring in “gifts” is hilarious! It has already paid for itself in the number of times it has stopped my cat from bringing in dead and alive animals. My carpets stay clean, I no longer dread seeing what “gifts” the cat left on the stairs in the morning, and I can just relax and enjoy my cats. They have the freedom to come and go at their leisure and I have the peace of mind that they won’t bring anything in. HIGHLY recommend!!

Great product, just works

I was an early backer on this cat flap, because my cat would bring in mice, birds, moles and voles almost every day. Sometimes alive, most of the time to eat over the cream carpets. I was desperate, and willing to edit for the kickstarter to evolve over 8 or so months.
I’m glad I did. I don’t even think about (let alone worry about) wildlife in my house any more, apart from the occasional notification from my phone that the cat has been denied access because she had something in her mouth.
It’s been so so smooth. Initially, my tortoiseshell cat’s fur was confused occasionally for prey, but OnlyCat included this footage into their training set, and I never have false positives (or false negatives) anymore. It. Just. Works.
One of the best uses of machine learning I’ve ever seen, a slick product, and a great support team. Thanks guys, you’ve saved my sanity.

Results from an outlier

Although it looks like I’m the outlier here, there are other sites where current owners are expressing frustrations like me. I was an original backer, got the unit installed, it had all sorts of random problems. My cat’s microchip from 2008 was working just fine with his old Sureflap unit but this new OnlyCat unit wouldn’t recognize his chip. So I tried a chip on a collar…. That worked sporadically. So I took him to the vet to get a brand new chip implanted & the unit would recognize it….. But not consistently. I have videos of my cat pawing on the door from outside (for like 50 seconds) trying to get in and it will not recognize the chip and allow entry. So I have to set it to ‘allow all comers’ meaning the local stray cat & racoons/etc. can get inside my home. BUT….. it did prevent him trying to bring in contraband one time since we installed it so THAT was awesome. OnlyCat ended up shipping me a replacement unit & when they got the original unit back, they charged me for parts to repair it. So caution to future buyers is DO NOT INSTALL THE UNIT PERMANENTLY until you know for certain it works because when you uninstall a unit that’s been mounted with screws, glue, caulk, tape it can come apart like mine did. I figured it was defective so don’t know why they would resell a defective unit but I don’t think I should have had to pay for the parts for them to try to refurb it. But I want the project to succeed and I’m in over $1000 USD already with this project (paid contractor 3 times to come install, uninstall, reinstall, international phone calls for support, cost of vet visit, cost of unit) so I’m not giving up now. Because they’re a small team, support has been unable to keep up with requests. At this point, I had a totally functioning Sureflap but it didn’t detect prey and that’s the ultimate goal so I’ll keep what I’ve got & hope they eventually get it to work with my cat having both an old & new chip so I can turn on the chip recognition. Right now, it is only recognizing if the entrant has prey or not….. So I’ve gone 3 steps forward and 2 steps back in technology by replacing my old Sureflap unit but these are the cost of being on the leading edge of new developments.

I cannot praise this company enough

I cannot praise this company and product enough. For years with different cats and in particular with our 2 year old boy we have had to live with them bringing in mice and rats and birds. Our young man brought in a live rat and dropped it in the bedroom for us, so kind! This cat flap is a game changer. I can go to bed and keep my bedroom door open and sleep easy. The company is fantastic as well, you ask a question and get an immediate response, they have also set up a fb page for purchasers of the cat flap so we can all share our experiences and help each other. They are fantastic and the product is out of this world.

Best product ever!!

Greetings from Denmark.
Thank you SO MUCH for pursuing the dream of making this product, it is the best!!! I have never ever hoped so much that our cats would catch a mouse/bird and we could see the product in action, but when they eventually did after 1 month, it was simply amazing, THANK YOU Onlycat Team! 100% worth the money

I’m super happy with my Only Cat Flap

I’m super happy with my Only Cat Flap. The app works great – it took me a bit of fiddling around at first to figure out how to customise everything myself, but once I got the hang of it, it was really handy.

After a while, I did run into a technical issue – the videos from the flap weren’t showing up in the app anymore. I sent them an email and got help the same day! They fixed the bug online really quickly. A couple of months later the same issue happened again, but again they responded fast and this time they sent me a whole new flap. I could send the old one back so they could check what went wrong. It all went super smoothly and throughout the whole thing, they were really friendly and helpful.

Now the new cat flap is working perfectly – no more mice getting in! (Although I had to laugh this morning because my cat left a mouse in the flap instead of on the ground… still outside though, so hey – it works!)

Also, the neighbour’s cat can’t get in anymore, which is a big win too.

Honestly, I really recommend this flap – and a big thanks to the team behind it. You’re fast, friendly, and super helpful – especially impressive for a startup!

And now I’m just enjoying watching the videos of my cats going in and out. Love it!

Great product and great team

Great product and great team. This cat flap solved our problem of our cats bringing us “gifts” ( both dead and alive) into the house. Since installation, the flap has sensed and prevented every attempt. Gives us so much peace of mind now. In addition to the product, the OnlyCat team is super helpful with any issues or questions. They always reply promptly. Highly recommend!

A smart solution to a real (albeit first) world problem!

In a world where smart technology seems intent on finding solutions for problems which don’t exist, OnlyCat have engineered a solution for a genuine (albeit first world) problem.

Most cat owners have experienced the challenge of their cat bringing in unwanted gifts, which can range from mildly inconvenient to full on (feline induced) blood baths – this is a cat flap which successfully fulfills all the features one would expect of a modern cat flap (chip entry, timed entry / exit, multiple cats) but with one added feature – an AI driven system to refuse entry to any cat carrying prey.

Sounds too good to be true, but it genuinely works – since we installed ours it has had an 100% success rate at detecting prey and preventing entry. Whats more, the system using machine learning to continuously improve.

This is a smart home product which even my wife endorses, and that tells you everything you need to know!

contraband dectected

We’ve had several incidents of contraband being detected already and we’ve only had the cat flap for around a month.
We’re not waking up or coming home to dead or half dead animals for which I’m extremely grateful. Would like the cats to stop catching prey completely but there you go.

This product brought peace and relieve to my mental state

We have 3 cats, 2 of them are young boys. They have terrorised me with their “gifts” , dead, alive,half eaten … we have tried the human traps but I still had to deal with the pray 🤮🥺. We installed cameras all over the house and i could see my cats bringing the little mice in, playing with them untill they got bored and let them go around the house or kill them. So upsetting. I did some research, and Onlycat came about and we have purchased it. I did not know I had to
wait for it quite a while, and my faith in solving the “gift”problem was down to 0 😕. I was so depressed coming home, thinking what am I going to find today.
After the cat flap instalation I felt relieved. No trace of mice or other prays. I thought, maybe it’s not working by detecting the pray or the cats just grow out of it. I was looking at history but did not pay to much attention untill yesterday evening, when I kept scrolling down and lots of ” Contraband detecting ” showed up. OMG ..Honestly, I am so relieved and happy with the product. It brought peace to my mind, so Thank you guys , you have no idea how much this innovation did for my mental health.👏👏👏

Brilliant use of AI

This is a brilliant use of AI. It works exactly as described, and it’s very easy to set it up using the app. It has thwarted every attempt our cat has made to bring in prey, and we can even track her comings and goings. Yes, it’s expensive, but you are paying for the conception and development of this amazing technology. We can now ask friends to feed our cat while we are away without worrying what they have to deal with.

Simply amazing

Simply amazing! Despite not being good at DIY I managed to easily exchange my old sure chip catflap for this one. It has stopped my cat from bringing dead birds, squirrels and rats into the house. Genius! Thanks so much only cat. You have saved my sanity!!

How did I live without this!

I never thought I’d be writing to sing the praises of a cat flap, but this cat flap is amazing.

I have two avid hunters who insist on bringing us ‘gifts’ on a regular basis. After the third live rat, AND having to replace the washing machine after an escaped mouse decided to set up home inside, we bit the bullet and invested in your cat flap, after 48 hours it’s already proving it’s worth, in the space of 5 hours it blocked entry of a live mouse and a live rat clasped in the jaws of our little raptors!

Genius! I’ve shared among my cat owning friends and I’m sure they will be making purchases soon!

Well done OnlyCat team, you’ve saved my sanity!

Life changing cat flap for me and my fluffy friend 😺.

This cat flap is incredible and life changing for me and my cat Enzo 😽. It’s an innovative microchip cat flap with AI technology which detects prey. I can now see cute videos/timings of my cat and I have complete peace of mind that he won’t bring any little friend’s home with him! Excellent customer service who’ve answered my stream of questions promptly. A very happy customer and a big thank you to OnlyCat ☺️👍🏼.

Remarkable product

I recently received my onlycat cat flap (beginning of March). It is an excellent product and has so far prevented my cat bringing in live mice twice. It is certainly a stress reliever and I am pleased that I bought it despite it being more expensive than most other cat flaps. Build seems high quality and support has so far been responsive when I’ve needed it (which hasn’t been often)

I absolutely love my new OnlyCat!

I absolutely love my new OnlyCat- the cost is worth it! It’s easy to set up and use, one can monitor cat movements thought the day via the app and it is excellent at blocking contraband entry. The timer function makes it easy for cat guardians to control when which cats go out and in and my sleep quality and quality is much improved as a result. I also want to say a big thanks to OnlyCat for resolving a logistics issue regarding my flap efficiently, professionally and graciously even though an error was made at my end. I’m now saving up to get one for my mum and dad’s cat!

This cat flap is worth every penny

This cat flap is worth every penny. I can’t say I was bothered by the leaves, dead mice and rats, but the cat would also bring in live mice and rats and let them loose around the house. Now I can sleep in peace knowing there won’t be mice dying behind plaster boards, or be woken up by rats.

Game-Changer for Smart Cat Flaps – Highly Recommend!

This product is absolutely fantastic, and the creators should be incredibly proud of their work.

I previously used a SureFlap but decided to upgrade to the OnlyCat. Installation was effortless—it fit perfectly into the existing hole, taking no more than three minutes to set up.

One of the standout aspects of this product is the continuous rollout of new features and improvements. I initially encountered an issue with the cat flap, but after reaching out to the company, they sent me a replacement within 24 hours—exceptional customer service!

While the app is fairly basic, it provides all the essential features I need to monitor activity and set up rules. Given that they are nearing completion of their project backer commitments, I expect further enhancements over time.

Fortunately, my main troublemaker has been on his best behavior lately, so there haven’t been any surprise “deliveries.” However, I can see the AI in action, accurately assessing and granting access without issues.

I have no doubt that this product will only continue to improve, and I’m excited to see how this company grows in the future.

Life changing

I waited a while before writing this review to ensure it was accurate.

This product is absolutely amazing – it has given me my life back.
My cat was constantly bringing in live mice and dropping them in the house for me to catch. Where one might expect a cat to eliminate a rodent problem, mine was actively causing one!

The Onlycat cat flap has worked flawlessly since installation, thwarting every single attempt my cat has made to bring a mouse inside.

Another major benefit: switching from a smart cat flap that ran solely on batteries to one powered by mains has been a game-changer. It was a constant hassle to monitor battery levels on my previous unit, and a dead battery risked trapping my cat inside or out.
The Onlycat unit includes a battery backup, ensuring it continues working even if the power supply is interrupted.

In summary, I would highly recommend this to any cat owner, especially those dealing with a pet that brings in prey.
Every detail of the unit is well thought out and refined.
