I love this cat flap

I love this cat flap! You not only don’t get intruders but it gives you the cutest videos of your cats and tells you which cat(if you have more than one) is most active. Haven’t experienced a cat trying to bring contraband in yet but all good so far! Very user friendly app and pverall great cat flap.

Worth every single penny

Worth every single penny . Absolutely brilliant. So many features including stopping unwanted gifts being brought in. Prevents unwanted guest cats coming in and reads their chip and records it. You know when your cats are inside or outside. You can keep one cat in for Egia vet appointment whist the other can still go out. It’s simple to lock the cat door quickly and unlock. You have clear video footage and alerts to your phone of your cats entry and exit and gifts. You can program if you want to keep your cat in at certain times and out. The door plays different sounds .
The list is endless. Yes pricey but best thing we bought.
Customer service is also excellent

Like other reviewers

Like other reviewers, it’s sounds silly but this cat flap has changed my life ! It really does work and put your mind at rest . My cat just a born hunter. Three ‘gifts’ in one day was the last straw for me . When I had teething problems understanding how the flap worked properly the company were very reactive.

Brilliant Catflap

I have been most impressed by the Onlycat catflap.
It has worked really well so far and has changed my life for the better as i no longer get anxious about finding dead prey in the kitchen when i walk in.
Love watching the cats coming in and out on the App too 🙂

5 stars despite some teething problems

There are still some teething problems with the device and app but I have to give 5 stars because it’s made a huge difference to my life. I rescued a local feral cat and no sooner had he got used to coming and going through the Sure Flap that I fitted, I was inundated with mice, shrews and birds on a daily basis. Chasing live mice round the house at 3 am or standing on dead small mammals was leaving me at my wits end. The OnlyCat has been amazing. For the first few days my cat tried to bring his catches in and only once foiled the flap by leaving a mouse next to the camera then retrieving it from inside. In less than two weeks he gave up trying. For months now he has only made a couple of attempts. I watched him one time catch a mouse in the lane outside my house and saw that he took it over to the barn that was his original home, clearly having learned not to bother trying to bring it in the house.
The biggest issue I have is that the flap doesn’t always close when it’s very windy. But I’ve stopped worrying about it as it generally happens on entry rather than exit so the flap is unlikely to allow my cat through with prey.

Worth the investment

The cat flap is not cheap… that being said, you do get your moneys worth. It was this or re-house my cat because her hunting was becoming legendary! But now I get to keep my loving cat and she gets to continue enjoying hunting. She literally just tried to bring a large rodent in through the flap for the first time. It has even denied her entry with a small moth before. It has also successfully blocked imposter cats from entering in the past. The app was aLeo easy to set up and use.

The reason I can’t give it a five star is because of how quickly it loses power when not plugged in. I understand it should be plugged in most of the time but I would hope that it could hold battery for at least an hour or so when unplugged. This is not the case. Also, I feel the release mechanism could be quieter. But that’s all.

Honest review

Honest review: This has changed my life! I know it’s expensive and I was hesitant to buy it as I wondered if it would work. But I have had mine a week now and it is life changing. I had tried everything before. Keeping our cat home from dusk to dawn, higher meat quality food, I even bought massive bells to put on my cats neck. Nothing worked and 4 times a night I would find guts, a live bird in the Christmas tree and mice running around at 3am. I was exhausted as my cat would be so loud chasing them about. When I tried to keep her in she would cry all night. I’ve had this cat flap a week and it has stopped 8 mice and 1 bird from coming in. I actually love to watch the videos back to make sure and the OnlyCat has had an accuracy of 100% so far. I went for the subscription version so it was cheaper upfront and then it’s about £7 a month. Worth every penny.

When it works it’s great but when it…

When it works it’s great but when it goes wrong it all goes very wrong.
I got my only cat catflap and it’s been great until 2 weeks ago. It has now developed a fault where the lock fails and my cat is either stuck inside or outside.
My only option is to send it back for repair and either have a hole in my window for my cat to move in all the local rats or close it up completely so my cat is stuck inside which feels very unfair. Will also have to pay out another £150 to have it reinstalled once it’s repaired.
Customer service has been very polite although a little slow to come back and not sure the cat is at the heart of this company, if it was maybe a replacement flap could be sent out before the faulty one being sent back so they’re not disrupted and I’m not left at risk of prey being bought in as ultimately this is why I bought the only catflap.

I never normally write reviews

I never normally write reviews, but I genuinely couldn’t not say something about Only Cats.

This has honestly saved our feet 😂 and, more importantly, saved our house from being constantly full of mice and birds! It has made such a massive difference for us, and we’re genuinely so thankful we found it.

It’s one of those things you don’t realise how much you need until you have it, and now I honestly never want it to go anywhere. Please, please never stop making this!

We are 100,000% recommending it to everyone. Thank you so much for creating something that has made such a difference to our home. We really appreciate it more than you know! ❤️

Great cat flap

Great cat flap! No more mice indoors and no more worries about it! Before, the cat woke us up almost every night chasing the mice he had brought into the house! Now, nothing at all! He doesn't even try to come in with prey any more! Really brilliant!

Super trappe pour chat

Super trappe pour chat! Plus de souris à l’intérieur et de soucis avec ça! Avant le chat nous nous réveillait presque chaque nuit quand il chassait les souris qu’il avait ramenées dans la maison! Maintenant plus rien ! Il n’essaie même plus de rentrer avec une proie! Vraiment genial!

Expensive but worth every penny

Expensive but worth every penny! In our first week of having one, our cats attempted 6 out of 7 night to being us a rodent but Only Cat stopped every single one! I can finally enjoy my home again without the fear of them bringing in live rats, birds, you name it!

Simply a great flap

We live deep in the countryside and we love that only our cat can get in and out.
The flap works perfectly. The app explains itself. It would be great if this flap came in a bigger size too.

Einfach tolle Klappe

Wir wohnen sehr ländlich, und genießen es, dass nur unsere Katze rein und raus kann.
Die Klappe funktioniert einwandfrei. Die App ist selbsterklärend. Es wäre toll, wenn es diese Klappe auch größer geben würde.

One of the best investments we have made! Our cats were continually bringing in small live mice and this clever cat flap prevents this.

Absolutely the best cat-related product we’ve purchased and it just keeps getting better and better. We get to sleep through the night now not having to get nervous every time we hear the cat door go, thinking we have to dive up to capture a mouse or bird
