    Top product. I've had the device for over a year and it reliably recognizes every gift from the cat.

    Top Produkt. Habe das gerät schon über 1 Jahr und es erkennt zuverlässig jedes Geschenk der Katze.

    The flap works perfectly (every prey item has been recognized so far), and even though the app still has some room for improvement, the support team responds incredibly quickly and creates customized solutions within the app for issues that don't yet exist in a general function. I've truly never experienced anything like it; I'm absolutely thrilled.

    Die Klappe funktioniert super (jede Beute wurde bisher erkannt) und auch wenn die App teilweise noch ausbaufähig ist, reagiert der Support unfassbar schnell und baut einem individuelle Lösungen in der App, für die es noch keine allgemeine Funktion gibt. Sowas habe ich wirklich noch nie erlebt, ich bin restlos begeistert.

    The Onlycat cat flap is the best thing I've ever bought. It has thwarted every attempt by my cats to get at mice, birds, etc. I'm overjoyed and still thrilled. Thank you, thank you, thank you!

    Die Onlycat Katzenklappe ist das Beste was ich mir geleistet habe. Tatsächlich ist bis jetzt jeder Versuch meiner Katzen mit Maus.. Vogel ..etc. verhindert worden. Ich bin überglücklich und immernoch begeistert.Danke Danke Danke

    The cat flap is definitely worth the money. The prey detection success rate is 100% so far. (Approximately 1 year of use)

    Controlling it via the app is very easy.

    The camera quality is also good.

    I would definitely buy the cat flap again.

    Die Katzenklappe ist auf jeden Fall ihr Geld wert. Die Erfolgsquote der Beuteerkennung liegt bisher bei 100%. (Ca. 1 Jahr in gebrauch)
    Die Steuerung über die App ist sehr einfach.
    Die Kameraqualität ist ebenfalls gut.
    Ich würde die Katzenklappe auf jeden Fall wieder kaufen.

    Since we got the OnlyCat cat flap, our lives have become much more relaxed. It reliably detects prey and blocks the cat's entry. The chip recognition works flawlessly.

    The range of functions and the configuration are comprehensive and incredibly easy.

    It's absolutely worth the price. We've only had to replace the flap once so far due to a mechanical fault, and the customer service was incredibly helpful.

    Seit wir die OnlyCat-Katzenklappe haben ist unser Leben deutlich entspannter geworden. Es wird zuverlässig Beute erkannt und so der Einlass blockiert. Die Chip-Erkennung funktioniert einwandfrei.
    Der Funktionsumfang, die Konfiguration umfassend und kinderleicht.
    Nur einmal mussten solut ihren Preis wert.wir bisher die Klappe wegen eines mechanischen Fehlers tauschen, wobei der Service super geholfen hat.

    Onlycat is extraordinarily effective in preventing feline perpetrators bringing in unwanted rodents etc. No more carnage under the piano or carcasses on the rugs. This product is expensive, but totally worth the piece of mind. Highly recommended. Reasonably easy to install and use. The associated app is will thought out and informative.

  7. Tyler Vander Vinne – Google

    Works exceptionally well. I had my doubts but it’s insane how good it works. Our fat ass cat fits through it too somehow

  8. Robert Arcon – Google

    The OnlyCat cat flap is by far one of the best things I’ve purchased. I’m so happy that I trusted the reviews I read. Now I can keep tack of our two cats better than before and we do not get any prey 🐭 delivered to us anymore. …

  9. Lisa Coppen – Google

    This is the best thing I think I’ve ever bought!
    We have a cat who is a prolific hunter, we were getting mice, birds even a squirrel brought into the house. The final straw was the mouse on the bed in the middle of the night!
    The cat flap was easy to install and the cat didn’t notice we had changed it. In the first week the cat tried multiple times to bring prey in but as he wasn’t allowed he soon stopped trying. We are a few years in now and he doesn’t even try to bring things in now he just leaves them on the lawn!
    It has made being in the house much more relaxing, we don’t come down in the morning worried about what creatures are running around. It really has made life so much easier.
    Thank you OnlyCat.
    Ps the customer service is top notch

    Amazing

  11. Liam Caffrey – Google

    Love it. Worth its weight in gold!!

  12. Hassani Sabbah – Google

    Best cat flap on the market. No prey any longer!!!

  13. Greg B – Google

    This is one of the best investments you can make, if rodents in the residence are frustrating you.
    Happy to spend the money and sleep at night. Costly machine, but worth every penny.

  14. Mark Kininmont – Google

    So, after installing the OnlyCat cat flap, in the first night it detected two attempted entries with prey! Then a little while later when our cat came back without prey the cat flap let her in! It really does work well………….

    This cat flap is the best purchase ever. No more 2am mouse massacres. Whilst the cat flap seems expensive, if you’re having trouble with mice then this is a brilliant investment. The cat flap detects contraband in micro seconds. Not to mention the cute snapshots you get of your furry friends when they go in and out of your house. No more mice and a peaceful, uninterrupted sleep. Thanks OnlyCat, couldn’t recommend enough!

    My beautiful little girl has it all now! She can come and go when she likes and doesn’t bring in surprise visitors to her Mummies great relief. She brought in a baby snake once…… I am very happy with OnlyCat and their support team.

    Has stopped the killer cat bringing in ‘gifts’. Day one of installation and it had already paid for itself. Also stops the other cat bringing in inanimate objects such as crisp packets and leaves! It is worth it.

    I know it’s disturbing to see so much dead wildlife but OnlyCat works so well it has actually curbed my cats hunting instinct. Because they can’t bring their prey inside they seem to have lost interest in the activity altogether. Before, my cats were wearing giant custom bells on their collar but nothing worked. I was chasing prey all over the house and often finding them dead – so stressful. This product changed my life and saved the lives of countless critters – worth every penny

    I have been using this product for just over a year. It’s been really good. My cat likes to collect animals from the garden, bring them in and use them as cat toys in the house at all times of the night. This isn’t great for the house as injured animals sadly make a mess everywhere. However, with OnlyCat she has been taught to leave them in the garden! It works off her id tag so it also stops other cats coming in. It’s a great product and I stand by its effectiveness

    Delivery took a while but great customer service when emailed. Quite simple to set up and get the app going. This flap has already saved us from my cat’s catches several times. Has relieved the anxiety I used to feel in the mornings at what mess I was going to find.
