Absolutely amazing piece of kit
We finally had enough and got the OnlyCat. It’s a straight fit replacement for the SureFlap we already have (seems to be the same plastic case just modified).
Since installing in mid December it’s never failed once. We have two cats and neither one of them has been able to bring anything in. The only thing is got wrong once that was it barred entry to our cat not carrying anything, however you can easily report these instances in the app and they soon get sorted.
My only slight niggle is that I wish there was a rechargeable version, I wouldn’t mind if that resulted in a massive battery pack on the door alongside it as running permanent power to a door that opens is a bit of a pain. Sure I could experiment myself with something like this but an approved battery from OnlyCat would give me peace of mind.
If you have a problem with cat gifts you will not regret buying this. Absolutely genius.
EDIT: Just bumped it up to a five star from a four star on the basis that we had a problem with our OnlyCat, partly their fault, partly our fault. It’s our first time dealing with the customer service and they are amazingly good and understanding of the issues we’re facing. They want to make the device work and clearly care about it. Deserves the full five stars just for that, a refreshing attitude.

Fantastic prey detection
The Onlycat cat flap has been in use here for 10 days and I am absolutely delighted. The 4 mice my two cats dragged home in that time were all detected, and access was reliably refused even over several attempts. It is an absolute game changer, after having had to catch mice alive or scrape them together in pieces almost every day at times.
It is a rather expensive cat flap, but given this extra prey detection feature it is absolutely worth the price.
The cats quickly worked out that without prey they get let in. Installation and using the app are easy. The app is not as polished yet as Sureflap's, for example, but I hope that will follow.
If a setting cannot be made yourself, support takes care of it within a few hours.
Shipping from the UK to Switzerland went perfectly within about 2 weeks. I would definitely buy the flap again!

Fantastische Beuteerkennung
Die Onlycat Katzenklappe ist bei mir seit 10 Tagen in Betrieb und ich bin total begeistert. Die 4 Mäuse, welche meine beiden Katzen in diesen Tagen angeschleppt hatten, wurden alle erkannt und der Zugang auch bei mehreren Versuchen zuverlässig verwehrt. Es ist ein absoluter Gamechanger nachdem ich bis jetzt teilweise fast jeden Tag Mäuse lebendig einfangen oder in Einzelteilen zusammenkratzen musste.
Es ist zwar eine eher teure Katzenklappe, aber angesichts dieser Zusatzfunktion der Beuteerkennung den Preis absolut wert.
Die Katzen haben schnell gemerkt, dass es ohne Beute den Zugang frei gibt. Die Installation und die Appbedienung ist einfach. Die App ist noch nicht so ausgereift wie beispielsweise diese von Sureflap, aber ich hoffe das folgt noch.
Können Einstellungen nicht selber gemacht werden, wird dies aber innert ein paar Stunden vom Support erledigt.
Der Versand aus der UK in die Schweiz hat innert rund 2 Wochen einwandfrei geklappt. Ich würde die Klappe auf jeden Fall wieder kaufen!

Warning to other customers
Despite these serious issues, the company refused to acknowledge the product as faulty. We tested it for one day using removable adhesive, yet they offered only a £250 refund because of minor cosmetic marks, ignoring all the functional problems when we paid an extortionate £500 for the product. Their responses were generic, dismissive and unprofessional, focusing on their manufacturing costs instead of the faults.
For the high price of this device, the quality and customer service were nowhere near acceptable. I wouldn’t recommend this product or this company and I strongly advise others to think twice before buying.
Constant AI responses and unprofessional messages telling us how they don’t make any profit and don’t pay themselves. I can’t believe a company would even say this to a customer. Clearly the reason why they won’t issue a full refund and have only ever offered replacements to other customers in the past and never a refund as per consumer rights.
I had such high hopes but it is not fit for purpose.Do not purchase!!!

Having been a cat owner all my life I was super excited to be welcoming 2 new kittens into my home, but equally terrified of the unwanted ‘presents’ that would undoubtable follow.
When I saw this product I was a tad dubious, how would it or could it work? But I am so glad I made the investment.
So far it has prevented them bringing me a feather, a flower bulb, various sticks, twigs and leaves, and an apple!
I have absolute confidence that when they are big enough to catch their first victim, I will not be chasing it around the house or even worse, unknowingly living with it!
And on top of that, the OnlyCat help team have been amazing, helping me set up various door policies to accommodate both my new kittens ever changing needs as well as allowing my existing older cat the freedom she is used to.
Genuinely, if you are thinking about buying this product – DO IT, you really won’t regret it.
Thank you OnlyCat for making my life and my kittens lives a better one.

I’m Witcher, a black cat, and I live with my adopted humans and my furry brother. First of all, I’d like to thank you for the great box and the interestingly smelling blue plastic bag you sent us—it’s so much fun playing with!
But seriously, what’s with this strange cat flap? Something’s definitely wrong! Whenever I want to bring my pack a plump, round mouse or a tasty baby rat, the cat flap won’t let me in! I’m the family hunter, and I’m used to bringing home one to three delicious prey items every day! My humans are unfortunately far too clumsy and stupid to catch mice themselves, and if I don’t bring them their meals, I’m very worried they’ll starve! Besides, we all used to have so much fun hunting a living mouse together at 3 a.m.! Are you expecting me to eat all the mice myself now? Do you want me to get chubby??? Think about it! …

Excellent product and excellent…
We’re having two active cats that used to bring in both birds and mice. That’s a thing for the past now.

Im VERY impressed with the customer…
The app is very easy to use. I already had a non ai cat flap fitted so I was able to easily slot this new cat flap in the space my old one was.
My cat was banned from the old cat flap for over 12 months due to bringing home rodent ‘friends’ and its so lovley she can come and go as she pleases again. Iv only had the cat flap a week, the new replacement only a few days.
I just wanted anyone else wondering if they should get one of these ai catflaps to know they 100% should! I havent got the best of health at the moment so it really has helped and i feel confident that i could go awaybfor a night or 2 and she would be 100% ok, i truly feel i can rely on this product to work while im not here

Tried to contact onlycat severall times, but they don’t respond at all.
After a few days i finaly got a response. They send me a new product. The problem was the wifi antenna of the device.
