  3. Andy Burrows – Google

    Fantastic no more creatures inside , no more dead little animals, worked really well from the 1st day installed . Worth the money , for piece of mind and not getting up at 2am to chase after a rat or mouse

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

  5. Steffen Bertelsen – Google

    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.

    Only cat has changed our lives and the lives of our cats for the better. Well with the purchase. I’d recommend this product and this company to anyone.

    We use it since two months and think it’s great, other cats keep out and we always see what’s happening. Expensive, but it’s worth it!

    Love our OnlyCat cat flap, we were chasing up to 3 live mice around the house every single day and now none. It’s been the best purchase we’ve ever made and the support team sorted an initial teething issue very promptly.

  11. Dr Renee – Google

    I could not be more delighted with my Only cat flap. I have two cats, one has to stay in at the moment, they both stay in at night and not only can it differentiate the cats, I can remotely open and close it which is such a bonus… and if that wasn’t enough, it stops any kills entering the house! It’s brilliant. Worth every penny!

    Fantastic

    Fantastic! Has worked perfectly since we got it and stops stray cats and dead mice. It’s really fun looking and the videos in the morning to see what’s been going on over night.

    This product has changed my life

    This product has changed my life. For the first time in years my cats no longer bring prey into the house. The relief is marvellous.

    LIFE CHANGING PRODUCT.

    LIFE CHANGING PRODUCT.

    Decent customer service & community.

  15. David Boyer – Trustpilot

    We both have our freedom!

    Fell in love with this cat. She is incredibly smart and no trouble in all ways but one. Dead animals and worse yet chasing live ones was taking a toll. Onlycat ended this hell. Almost 2 years that only the cat came through the door. The bond between my fuzzy friend and me continues to grow. All good no bad. Onlycat is worth every penny and if it wears out before my cat, I will buy another. She loves her freedom, now I have mine!!!

    Greatest thing I have bought we have…

    Greatest thing I have bought we have our life back and sleep !

  18. Karen England – Trustpilot

    Absolutely brilliant!

    Incredible product. It’s changed our lives- no more rats, mice, birds in the house every morning. And the support service from Onlycat is superb – very helpful & responsive. One of our best purchases ever! And the videos of attempted entry (denied!) with contraband are a constant source of entertainment!

  19. Michiel – Trustpilot

    Great product

    Great product, works well and easy to replace our existing Cat Flap.

  20. Gail Kane – Trustpilot

    The best piece of kit ever!To anybody thinking of buying this

    To anybody thinking of buying this, I say go for it.
    My cats fondness for bringing mice in both dead and alive was causing so much stress.
    The last straw was treading on a dead mouse in the middle of the night.
    Customer service is exemplary.
    If you want your cat to have freedom but hate the “presents” this is for you.
    The peace of mind justifies the cost.
