The OnlyCat saved our sleep! It works exceptionally well and has kept out every mouse and gopher our sweet cat has tried to share with us since installing it. It has also blocked a feral cat and many raccoons! The staff at OnlyCat are wonderfully attentive as well when we had to troubleshoot connection issues. Thank you for giving us peace of mind and good sleep again OnlyCat!

Excellent. We have had this cat flap for a number of months and we have had no unexpected visitors. When out cat tried to bring in a uninvited visitor (rat) 🐀. He was locked out. This has been an excellent investment. …

Life changing….if you’re thinking about buying OnlyCat, just do it!! Their customer service is 10/10. I’ve not had one incident in nearly a year, faultless every time.

This thing is awesome. Its accuracy is remarkable. Both times that our cat tried to bring contraband inside (ie a mouse and a lizard), the cat door locked and denied her access. This is definitely worth the purchase.

OnlyCat works as advertised and has given us peace of mind. No more unwelcome guests! Our cat learned to use it very quickly and we can see he knows that when he comes without any “contraband” he can get in easily. Excellent customer service and an easy to use app on the phone makes this a product we’re glad we bought. Highly recommended.

A Real Game Changer for Cat Owners

This incredible gadget is heaven sent for anyone who dreads coming home to yet another feline murder scene. My cat is a dedicated mouse hit man and I’ve spent the last two years finding disgusting surprises – dead or alive – throughout the house. Turns out we didn’t have a mouse problem until we got a cat. He recently upgraded his skill set to rats, and something inside me broke. Although this cat flap cost more than my last holiday, it’s made life so much more relaxing. I no longer have to wonder what carnage I have to come home to or what on earth I’ve trodden on in the dark at 3am on the way to the loo. Thank you, OnlyCat. No really, THANK YOU.

This product changed our lives

This product have changed our lives. No mouse (dead or hurt) are waiting out side the bedroom door in the morning. It’s 100% amazing. This door have blocked our cat every time he tries to get in, carrying a mouse in his mouth. It has also blocked a big rat, trying to get in by itself.

I had this installed and within 1 hour saved me from having a pigeon in my house! Within 2 hours it stopped a mouse running round and now 3 days in stopped my cat bringing a rat indoors! This is the best product I’ve purchased and well worth the money, I just wish we had it sooner! With my second cat being let loose in a few days it has reduced my anxiety ten fold. THANK YOU ONLYCAT.

Life Changing

Only Cat has literally changed my life. No more living in fear every time the cat flap opens and no more chasing mice round at 3am. As someone who is irrationally terrified of mice my only regret is not buying OnlyCat sooner.
Martin and Tomas should be very proud of their creation. The customer service they provide is 10/10, always getting back to you quickly with any queries!
I was hesitant about it the cost, but it’s worth every penny.

Brilliant

Purchased the Onlycat after one of my cats brought a live rat in to the house. I am really pleased with it and its working brilliantly, great having the option to set curfews. Customer service is second to none. Emma had the patience of a saint helping me set it up which was’nt difficult, I’m just bad with technology !!! Would highly recommend

I am pleasantly surprised and also delighted by how the prey detection works. We have had the cat flap in use for about four weeks now and 5 out of 5 alerts were correct. The app could be developed further in scope and design, but it runs stably.

After many 3am surprise deliveries from my cat (mouse,rat,bat,bird) I began my search for a catflap that could keep these surprises outside and not running around my bedroom.
Enter Onlycat….
This is a one of a kind and remarkable!
It works with an AI camera that learns to recognise my cat and allows her access in/out of home, but it also recognises when she brings home contraband and locks the door and keeps her outside.
It has an app,which sends a little video each time the catflap is used, which is really helpful to know when she’s in/out/barred temporarily and it brings me immense peace of mind.
I cannot recommend it enough.

Absolutely Brilliant!

Absolutely brilliant device! Yes it’s expensive but it’s worth the money given the tech involved! My wife and kids love our cat but go into panic mode if he brings them a ‘present’! This cat flap stops him in his tracks literally! Is very effective stopping the cat bringing in contraband and also very funny watching him try through the app! Also due to its microchip recognition, we are now looking to introduce a kitten to the household, with the confidence he can’t get out while allowing our other cat to carry on as normal. Great bit of kit!

It was a tricky start as the latch wasn’t popping up, allowing an outside cat to come in and spray, but after a chat with the very helpful support people and a custom rule being sent to our cat flap the sprayer hasn’t been able to get in, and we don’t even see it trying any more. One aspect that was interesting is the flap making an angry meow noise when it detected the spraying cat, that was quite effective but needed changing as they seem to have got used to it.
Our cats were nervous about it at first and we had to help the second cat through manually a few times before they got the idea but they are happy with it now.

Best cat flap ever

The flap works flawlessly. Prey stays outside. At last I can sleep through the night again — as a senior, a night's sleep is "sacred" to me. The flap is expensive, but I would buy it again in a heartbeat. Installation is fairly simple, and the onlyCat support is absolutely great: if you have questions you get help very quickly and very kindly!

Beste Katzenklappe aller Zeiten

Die Klappe funktioniert einwandfrei. Beute bleibt draußen. Endlich wieder nachts durchschlafen, für mich als Seniorin ist der nächtliche Schlaf „heilig“. Die Klappe ist teuer, aber ich würde sie trotzdem sofort wieder kaufen. Die Installation ist relativ einfach, und der onlyCat support ist super toll, man bekommt bei Fragen sehr schnell und freundlich Hilfe!
