    Excellent cat flap. Especially since our house is now mouse-free again. Wonderful! I highly recommend it. Works perfectly.

    Sehr gute Katzenklappe. Vor allem weil unser Haus jetzt wieder Maus frei ist. Herrlich. Kann ich nur empfehlen. Funktioniert super

    I splashed out after my boy brought a live rat inside. 6 months in and I’m soooooo glad I did. It works a treat and stops him in his tracks.
    It also stops the neighbours cat coming in.

    Fantastic bit of kit keeps 100% intruders & contraband out … well worth the money 💴 …

    We have two cats and the flap works perfectly fine. No mice or birds anymore

    Fantastic innovation! Our Onlycat has saved us lots of time and worries, no more searching for alive or dead prey in the house.

  6. Rosario Aguilar – Google

    This is an amazing way of keeping unwanted gifts from coming into the house. I can also monitor the coming and going of the kitties. Customer service is excellent and product reliable!

    Game changer! We were concerned how well it would work and how our cat would adapt to it. It’s been 100% correct and our cat has very quickly adapted to it. He still tries to bring things in and it never lets him. It hasn’t put him off coming home. Very quickly after attempting to come in with ‘contraband’ He gives up and comes in. We have also enjoyed watching the videos of him attempting to bring things in . Well worth money!

    Our experience has been great with only cat. Joined on the very early stages, and it’s worth every penny. Yes it is expensive, but It gives us peace of mind or cat can come and go as she pleases without bringing in any ‘friends ‘. This works especially well if we are away at work or somewhere else, we don’t have to just keep her locked up….. As nobody wants to come home to unwelcome guests!

    Best product available for this application. Will change your life and your cat’s life for the better!

    We used to have a standard cat door that just open normally. One of my cats would bring in live rats and mice from a farm nearby every night. So I would be up at 3 in the morning chasing a rat through the house with a towel(for hours some mornings). This only cat smart door has never failed. It stops her bringing anything in, also stops neighbor cats getting in. It keeps record of who went in and out throughout the day so we know who’s home and who’s not. It is also handy that you can set it to keep on cat in and leave the other out. This is handy for scheduled vet visits to make sure they are around when you need to take them.

    Can’t stress enough how good this is.

    We love this product! It works perfectly. No more mouses in the house! 🙂👍🏼 the price is a little bit expensive but the qality is good and the important thing is that it works really good. So we are happy with it! 🙂👍🏼 …

    Life changing for the wife who was at the end of her tether with the dead and alive creatures getting brought into the house. It’s worked flawlessly for well over a year now.

    Onlycat is an amazing product, it’s stopped at least 10 mice from being “gifted” in less than the year we’ve had it. Very low false positive detections, great support team. The app is very good.

  14. Tommy Butler – Google

    The Only Cat has been a game changer for us. It is easy to put in, really easy to operate via the app and has prevented upwards of 200 presents from our 2 cats and we only have it 6 months. I would thoroughly recommend OnlyCat to any cat owners!

  15. Sandy Snyder – Google

    BEST PURCHASE EVER! My indoor/outdoor cat was bringing me live critters all through the night, and now I can sleep in peace! I get so much enjoyment watching all her attempts to bring in “contraband.” She is quite the huntress! I’ve also used the microchip detection to make sure only she can come in (we had oppossums and raccoons try!). I also love that it it tracks and notifies me of her exits and entrances. It’s truly the best purchase I’ve ever made.

    Simply amazing, game changing for cat owners. No more presents from our two cats since installing OnlyCat cat flap over a year ago. App is also top notch

  17. jennifer heckert – Google

    This cat door is truly amazing. We live in an area of rural Canada and our cat is a prolific hunter, bringing in an array of dead and live prey on a regular basis. The door worked immediately and seamlessly from the start and our cat soon learned to stop trying. I am relieved to no longer have to clean up mangled bodies strewn all over the house nor catch half dead prey that’s flying or scurrying around inside. Thank-you OnlyCat!!

    Worth every penny. No more pulling the house apart at 2am because our beautiful Chloe wants to play with her new toy indoors and doesn’t get the concept off rats living outside only.

    Already have this product for more than 1,5 year. And it really works great! No more (living) animals brought into the house by my beloved cat!

  20. Adam Turner – Google

    Is 1000% worth it. Our cat was bringing in voles and rabbits on a weekly basis and now none make it into the house. Fantastic product. Absolute game changer
