Was very dubious but can honestly say…

Was very dubious but can honestly say this device is brilliant! Even from scanning your cats chip, that in itself is a game change because having had to programme my cats in on other microchip flaps, it’s really stressful!! This just reads your cat as soon as they go near it. But obviously the amazing part is stopping unwanted guests, it’s done exactly as promised!!!! Amazing and worth every penny. App is great to use as well.

Works brilliantly

Admittedly it's a fair amount of money to lay out for a cat flap. But it works perfectly and keeps out everything the cats aren't supposed to bring in.
The build quality feels high-end, and the support I needed for fitting it into a metal door was fast and knowledgeable. So I can give a full 5 stars here with a clear conscience.

Funktioniert hervorragend

Erst mal ist es ein recht hoher Betrag, den man für eine Katzenklappe hinlegt. Sie funktioniert jedoch perfekt, Hält alles draußen, was die Katzen nicht mitbringen sollen.
Die Verarbeitung wirkt hochwertig, der Support, den ich für Einbau in eine Metalltüre benötigt hatte, war schnell und kompetent. Von daher kann ich hier mit gutem Gewissen volle 5 Sterne geben.

Rats in the kitchen ! No more….,

I was starting to go crazy with the constant gifts my cat was bringing me.. he has a preference for bringing me live creatures and had moved on from bringing baby mice through to small rats! That’s when I lost my mind.. rats in the kitchen!!! Researched all the options and Only Cat had the best reviews … I did wince at the price but it seemed the only option! Well I’m delighted to say it worked straight away.. Hugo was thwarted in his missions successfully 11 times! And now he’s stopped trying!! Total success he’s got the message! The device was easy to fit in my existing cat flaps space, simple to set up and provides me with entertainment and peace of mind! Worth the money to get rid of a really bad problem!

Sanity restored

My two cats turned out to be serial killers the like I have never met before. I was becoming quite depressed by the dead, disembowelled or near dead creatures which I was faced with every single day. Apologising to visitors for the blood bath going on around us. I didn’t sleep properly as was up several times a night catching mice or rescuing half dead animals – it really started to get to me and I even wondered how much longer I could cope with the killing. When someone told me about this device I thought it was a joke and not real. But there it was. I hardly even looked at the price as was desperate and all the reviews were hugely positive. Onlycats flap arrived and was really easy to set up. It is quite unbelievable – I cannot express how positively my life has been enhanced by this device. The killing still goes on but not under my bed or in the bathroom. I don’t have to watch where I step when I get up. It felt expensive to shell out initially but this expense is outweighed by the 100% success rate. It has saved my sanity. Also as a sidebar I am now pathetically hooked on watching the comings and goings of my boys – whether they are in or out, and most likely annoyingly sending unwanted videos to my friends of the contraband shots. If your cat brings in prey get this cat flap – 100% brilliant.

This is truly a great product

This is truly a great product. Very easy to setup when it arrived, it was then a case of waiting for “contraband” to be detected!
Cat flap stays locked despite our catch trying numerous times to get in.
Also stops other cats it doesn’t recognise chip wise, but with this device we can now see what other cats are hanging around. Brilliant product, would highly recommend it if you have prolific hunters!

A Game Changer!

Having the new cat flap installed has been a complete game changer for us.
One of our cats is a real hunter and when it’s full moon, wow is Yogi Bear a nightmare.
So we’ve gone from being woken up a lot with his calling to our other cat, Holly, ‘look what I’ve got’ dumped at the bottom of the stairs, to restful nights.
I will be honest as I was a little suspicious it wouldn’t work after spending so much money, but yes it does, especially with the extra lock mechanism fitted on it. Yogi is one smart cat and would have surely worked out the button to open it.
So like the saying ‘computer says no’, Mr Happy Catflap ‘says no’ to Yogi with his latest catch. Happy days!!

Good stuff! Been reliable for almost a year now 🙂 The first detection of the mouse my cat tried to bring in was stopped by their AI sensor 🙂

Bra saker! Har vært pålitelig i nesten et års tid nå:) Den første deteksjonen av mus katten min prøvde å bringe inn ble stoppet av AI sensoren dems:)

We've been using OnlyCat for a month now, and the flap works perfectly! It has successfully prevented our cat from bringing home "smuggled goods" several times – and now, clever as a cat, she's apparently learned that there's no point in bringing them in; for the past few days, she's been sitting in front of the flap without any. Since the exit can also be locked, we can keep her from catching birds in the early morning hours. In short: a brilliant invention, worth every penny (or penny; it does come from Wales...)!

Wir haben OnlyCat seit einem Monat im Einsatz und die Klappe funktioniert perfekt! Unsere Katze wurde mehrfach erfolgreich daran gehindert, mit Beute ("Schmuggelware" genannt) ins Haus zu kommen - und nun hat sie, schlau wie eine Katze, offenbar gelernt, dass es keinen Sinn macht, Beute anzuschleppen, die letzten Tage hat sie immer ohne vor der Klappe gesessen. Da auch der Ausgang gesperrt werden kann, können wir sie in den frühen Morgenstunden davon abhalten, Vögel zu fangen. Also kurzum: Geniale Erfindung, jeden Cent (oder Penny; kommt ja aus Wales...) wert!

Great product, well worth the investment. Our two kitties were bringing in 2 or 3 mice a day, and even managed a rabbit once. Total pain cleaning up after them.The OnlyCat has been 100% successful at denying entry when they’re carrying gifts. I appreciate the really well designed mobile app too, very fast to get up and running.

My OnlyCat is worth every penny. It works perfectly (after we created an air gap because our door is encased in metal).

So interesting to see when our cats come and go. Best part is that I haven’t had to clean up rodent guts in the garage or deal with half dead rodents that the cats wanted to bring home as a gift for me.

Since buying this product, my cat’s reign of terror has come to an end. The days of barricading myself in various rooms when mice and birds have been brought inside (both alive and dead) are over and I have never known peace like this. The anxiety of not knowing what I’d find when I got home or when I woke up has gone. It has also stopped other cats in the area coming in. The app is great and gives peace of mind if you’re away and wondering if your cat is back home safely. I would honestly give this more stars if I could – it’s worth every penny.
