Amazing! So worth it, such a great purchase. Has given us peace of mind and saved so many mice, rats & birds being brought into the house since we fitted it last summer.

One of the best purchases I’ve ever made! We sleep soundly at night in the knowledge that OnlyCat won’t let our cute killer in with his latest “gift”. Customer service is fantastic too. If you have a cat and it is a prolific hunter, you need one of these. I would thoroughly recommend.

Best purchase I ever made. I sleep so much better knowing that my 2 cats will have to leave their ‘gifts’ outside

Brilliant cat flap! It not only saved us cleaning after many unwanted gifts (or I should say, contraband! 😄) but it’s also made it easier and given us more flexibility in managing when our cats can go in and out (we keep them in at night so the one way door is super helpful). The app is a bit clunky but very functional, and it has little things that make it fun to use too. I love for example the notification photos of the cats coming in, they’re so funny from that angle!

Awesome product, it has stopped one of our neighbors cats coming in every night to eat our cats biscuits, he tries every night, but his name is not down on the list, so entry is denied. It has also stopped one of our cats bringing in mice (contraband)….it’s not cheap but our cats are now safe in their own home and we don’t get woken up in the night by our cats playing with a mouse they brought in.

I was skeptical at first with this would actually work, but believe me it is saved us many times I haven’t had a mouse in my house since installing. It fit perfectly into my existing sureflap Door and surprisingly the cord is not that noticeable when you hugged the corners of your wall. Highly highly recommend.

This is the best buy I have made for a long time! I was concerned about the price but it has done exactly what is meant to do! And worth every penny! I fed up with my cats bringing in live animals and the feeling of a live mouse running around my house was just the most awful feeling! But not anymore!
Secondly the customer service is bloody brilliant so helpful and they have sorted any little issues out remotely and super quickly. They always respond to emails the same day! Keep up the good work !!
If you are considering a cat only cat flap you will not be disappointed!
Shame I can’t upload a video its hilarious watching your cat try multiple times trying to get in the cat flap. Just brilliant lol

Best investment ever. Having two cats, who brought many “presents” in the past (including living mice, who occupied our kitchen), by now the flap protected us from 51 contrabands in one year (plus one alien cat and two foxes). 100% recommendation.
(And BTW the videos on the app are great to show to other people)

This is an absolute treasure! You can’t imagine how much rodents, snakes, lizards this thing has helped us to keep out. It works so damn good. This is the best investment ever! So easy to install and the UI is super easy to get hang of!

My 2 indoor/outdoor kitties bring in critters. Some I have to rescue, some try to make my house their new home and some had already gone on to glory. We have tried collars with bells and yes, keeping them inside. Nothing this far has worked. So I came across this cat door and thought I would give it a try. So far it has helped immensely. It stops my cats from bringing in “contraband” so I don’t have to deal with it in my home which is nice. I have not yet had a bad read, which is nice. I hope that keeps up. I’m able to set a curfew for my cats so they can always come in but it doesn’t let them back out overnight. Programming their chips was easy. I’m stories it read them. My cats were apprehensive for the first week or so, even though they were accustomed to a cat door. But now that they are used to it, they come and go without bringing in their latest catch. Worth every penny. And now we know which cat was the culprit for which critters were found in the house (yes, they have a type).

After 2 years of chasing down birds and mice brought in by our cat I half-jokingly looked up an AI solution to find OnlyCat.
This is an absolute life changer and worth every cent if you have cat allowed the freedom of being in or outside.
After-service and support we’ve received is also top-notch!

Thank you OnlyCat team.

Keep the mice outside where they belong!

Our cat is a prolific hunter, he often brought live mice in which we all chased around the kitchen and dead mice that he used to like to bring up to us in bed, waking up with a dead mouse in your bed has to be the lowest of the lows!!! So we invested in OnlyCat which although expensive was actually the best purchase we have ever made, not only did it put an end to the wildlife in the house it also meant we could set a curfew for him, so now once he comes in after 9pm he can’t go out again until 5am. You have an app which lets you see their movements in and out and the OnlyCat team are so helpful and extremely quick at responding if ever there is a problem. It really is a no brainier to get this cat flap.

Works exactly as described.

This door has worked perfectly as described. I was an early adopter because I have a cat that brings in endless “stuff”. That stopped the day OnlyCat arrived. The company quickly responded to a question and the app and UI have only gotten better.

The best bit of tech I think I have…

The best bit of tech I think I have ever bought! Our cats were prolific hunters, especially of rats (we live rurally) and mice. The times that we have spent rescuing live ones from behind cupboards, kitchen units and furniture is beyond a joke!
Since purchasing the onlycat cat flap we’ve had none of this. They still try – admittedly less now – but nothing has managed to get inside. Life changing!
Oh, and an added bonus is the hilarious footage of their little faces when they come through the flap, worth the purchase price for that alone!
Customer support is amazing, very quick response to queries – the app is fine, nothing too wow but user friendly and fit for purpose. Facebook group is helpful and informative. What’s stopping you?! Get buying!

Great flap!

This flap is simply top class. It was actually bought for my tomcat, who was a keen hunter, and I spent many hours in the night catching all sorts of animals, from voles to bats, martens and so on. Sadly he passed away before I received the flap.
But his 2 successors have also tried more than once to bring something in from outside, and it works flawlessly. Anyone who has spent hours catching animals will appreciate owning a flap like this. It is worth every euro; it gives me back a large piece of quality of life (sleep).

Super Klappe!

Diese Klappe ist einfach Top. Eigentlich wurde sie für meinen Kater gekauft, er war ein fleißiger Jäger, und ich habe viele Stunden in der Nacht damit verbracht irgendwelche Tiere zu fangen, von Wühlmaus bis zur Fledermaus, Marder usw. Er ist leider verstorben bevor ich die Klappe bekommen habe.
Aber seine 2 Nachfolger wollten auch schon öfter was von draußen mitbringen, und sie funktioniert tadellos. Jeder der Stunden damit verbracht hat irgendwelche Tiere zu fangen, wird es schätzen so eine Klappe zu besitzen, sie ist jeden Euro wert, sie gibt mir ein großes Stück Lebensqualität (Schlaf) zurück.

Well Onlycat has proved it’s worth

Well Onlycat has proved it’s worth; no more chasing mice around the bedroom at silly o’clock in the morning or trying to stop disoriented flying things head butting windows & doors. It also has the neighbours fluff ball totally baffled so only(my)cat. Sleep & only paying to feed one cat, what’s not to like 👍

OnlyCat is Phenomenal

What a phenomenal product. We took on an outdoor cat, who is a prolific hunter, who soon worked out she could use the cat flap to bring in mice, rats, squirrels, birds and rabbits. Cue either blood and guts, or chasing live and scared animals around the house. The stress in the mornings waking up to that weird meow noise when you knew she had something was horrendous. Her eating a live mouse under the bed was particularly memorable.

This product has had the biggest impact on our quality of life in the last five years than anything else we’ve purchased. We’ve had no issues (touch wood!) and any questions around connectivity and the like are answered promptly.

I was a kickstarter member for this product as we were so desperate for a solution, and I felt a bit of pride watching the lads on Dragons Den. No surprise they got the backing they thoroughly deserve.

OnlyCat is superb.

Life-safer of a product

Life-safer of a product! Haven’t had a single prey indoors since we had it installed! The UI is not the most intuitive, but easy to use when you get the hang of it. Also, the power cable does make it less aesthetically pleasing when installed compared to other options – but the competition can’t handle prey detection, so that’s a no-brainer! Would recommend this to any cat-owner!
