I love having this cat door! It works reliable and already has stopped a few attempts to bring in something… It gives me a peace of mind and my cats love the freedom of coming and going as they please.

My only suggestion for further improvement is to apply a overlay to the video when a mouse is detected… Being someone with a really bad phobia (reason i bought this product) , its hard/impossible for me to open the app and see pictures of them. Or maybe include it in the filter logic .

Amazing cat flap, between my 3 cats who bring presents home daily this has been a life saver. Any questions and small issues I had initially setting up the profiles for the cats was dealt with straight away Support staff have been fantastic. Yes would love to see the app it self have a face lift but imagine that will come in time.

Great catflap, works as intended so far, has stopped several contrabands and other cats which is why I bought it.

The app is developing over time and has improved during the time I have had it, have had some issues with not letting out my cat but a quick reboot fixes that.

Keep up the good work, its a Great product!

I have had my OnlyCat for nearly a year now and it is amazing. Easy to set up and program, and has blocked every attempt by my two cats to bring home prey. The video feature is very useful (and sometimes hilarious!). The app is user friendly and the team are quick to respond to any queries. Loving the new updates on the app and overall well worth the investment.

I was an early adopter of this amazing product, so nearly two years of faultless operation. I can honestly say this is one of the best tech purchases I have ever made and has proved to be totally reliable.

Saved a lot of stress

Super accurate! We have 2 cats and everything stays outside! Detection is super, we can customise it when they go outside and we absolutely love this product. Saved a lot of stress!

My cat thinks he’s in the Serengeti…

My cat thinks he’s in the Serengeti and is out hunting all the time. This flap has been a complete game changer for us. No prey has got through so far and, in fact, he’s even stopped trying to drag creatures in now as no ‘contraband’ has been detected on the camera for months. We were nervous about spending such a lot of money on a cat flap, but it is honestly been worth every penny. If you’re hesitant, go for it! It’s a fantastic product.

Brilliant

OnlyCat has created a very innovative product that allowed me to have peace of mind and my cats absolute freedom. It works very reliably and the app gets new features now and then. They even support integration into home assistant through the cloud although I will be even happier if they manage to add a local access. On top of that interactions with the customer service are a pleasure. They are extremely quick in responding and very helpful.

OnlyCat saves our night's sleep

The cat flap has meant that the cat has not been allowed in with prey since it was installed. It is expensive, but in our opinion it has already paid for itself, since the night-time mouse hunts have stopped completely. We needed a little help getting it going; support replied quickly and helpfully. The product and the company are recommended!

OnlyCat redder nattesøvnen

Katteluka har gjort at katten ikke har hatt adgang med bytte siden den ble installert. Den er dyr, men etter vår mening har den allerede betalt seg, siden det er helt slutt på nattlige musejakter. Trengte litt hjelp med å sette den i gang, support svarte raskt og hjelpsomt. Produktet og firmaet anbefales!

Great, apart from a few compromises

Fantastic cat flap! What a relief for our lives. Technically it works flawlessly and has detected every prey animal so far.
Only three things to criticise:
1) The opening of the flap is (slightly) too small. Compared with the previous flap (from PetSafe), my normal-sized tomcats have more trouble getting through and one of them still refuses to pass through at all. I could not position the flap higher, as I had to fit it into the existing opening in the cellar door.
2) Fitting it into the thick wooden door (with a tunnel extension) was quite difficult, because the fixing screws (which were too short anyway) have to be threaded from the outside into the small holes of the inner panel. That makes sense when fitting into a glass door, but with a thick door or a wall it would be better if the outer part and inner part could be screwed directly into the wood or the wall from their respective sides.
3) "Thanks" to Brexit, on top of the (justifiably) high purchase price and shipping costs you also have to pay EU customs duty!

Großartig - bis auf ein paar Abstriche

Phantastische Katzenklappe! Welche Erleichterung für unser Leben. Sie funktioniert technisch einwandfrei und erkennt bisher alle Beutetiere.
Nur drei Dinge sind zu bemängeln:
1) Die Öffnung der Klappe ist (etwas) zu klein. Im Vergleich zur vorigen Klappe (von PetSafe) kommen meine normal großen Kater schwerer durch und einer verweigert bis jetzt überhaupt den Durchgang. Ich konnte die Klappe nicht höher positionieren, da ich sie in die bereits vorhandene Öffnung der Kellertüre einbauen musste.
2) Der Einbau in die dicke Holztüre (mit Tunnelverlängerung) war ziemlich schwierig, da die Befestigungsschrauben (die sowieso zu kurz waren) von der Außenseite in die kleinen Löcher der Innenverkleidung eingefädelt werden müssen. Beim Einbau in eine Glastüre macht das Sinn, aber bei einer dicken Türe oder Mauer wäre es besser, wenn man den Außenteil und den Innenteil von der jeweiligen Seite aus direkt im Holz oder der Mauer anschrauben könnte.
3) "Dank" Brexit muss man noch zu den (gerechtfertigt) hohen Anschaffungskosten und Versandkosten einen EU-Zoll bezahlen!

Five stars from us.

We’ve had our OnlyCat cat flap for a couple years now, I guess we were early adopters. We absolutely love it and thanks to updates to the device and app, it just keeps getting better.
One of our cats is a constant hunter and she loved to bring animals in the house.
The OnlyCat flap has stopped that. Thank goodness! The app is customizable so we have our door configured for several situations. Some examples are what we call IN-ONLY, Curfew and Quarantine. We can allow them to come inside only but prevent any of them leaving again or in the case of Quarantine set it so only one is allowed or barred as the case may be. You also set for scheduled events (our curfew setting). How you set it is up to you and OnlyCat engineers will help if you struggle with the setup.
We absolutely love our flap and will not be without one now. It’s expensive but worth it in our opinion. Five stars.

Stops unwanted gifts

Our multi cat household means a lot of unwanted gifts. No more. It’s not cheap, but does what it is supposed to. The app allows specific rules for individual cats. You can see the toing and froing of daily cat life. It’s useful to see who is in or out at a glance. If you’re away from home you can monitor from afar. In summary, impressive.

More than paid for itself.

We must’ve spent many times more than the price of OnlyCat in repairs caused by rodents brought in to the house by our two cats.
Since installing, three attempt have been made to bring in mice or larger rodents, all thwarted. Paid for itself many times over.

Genuinely works

Genuinely works. Saves us a lot of hassle and worth the time to teach them how to use a cat flap.

A really good cat flap

A really good cat flap. Fitted perfectly into my old Sureflap space. Connected to cats chip immediately and without stress to the cat. It’s already prevented contraband so I’m really happy with it.
Customer service prompt and helpful as initially had a problem getting the flap linked to the app but all sorted.
