How did I live without this!

I never thought I’d be writing to sing the praises of a cat flap, but this cat flap is amazing.

I have two avid hunters who insist on bringing us ‘gifts’ on a regular basis. After the third live rat, AND having to replace the washing machine after an escaped mouse decided to set up home inside, we bit the bullet and invested in your cat flap, after 48 hours it’s already proving it’s worth, in the space of 5 hours it blocked entry of a live mouse and a live rat clasped in the jaws of our little raptors!

Genius! I’ve shared among my cat owning friends and I’m sure they will be making purchases soon!

Well done OnlyCat team, you’ve saved my sanity!

Life changing cat flap for me and my fluffy friend 😺.

This cat flap is incredible and life changing for me and my cat Enzo 😽. It’s an innovative microchip cat flap with AI technology which detects prey. I can now see cute videos/timings of my cat and I have complete peace of mind that he won’t bring any little friend’s home with him! Excellent customer service who’ve answered my stream of questions promptly. A very happy customer and a big thank you to OnlyCat ☺️👍🏼.

Remarkable product

I recently received my onlycat cat flap (beginning of March). It is an excellent product and has so far prevented my cat bringing in live mice twice. It is certainly a stress reliever and I am pleased that I bought it despite it being more expensive than most other cat flaps. Build seems high quality and support has so far been responsive when I’ve needed it (which hasn’t been often)

I absolutely love my new OnlyCat!

I absolutely love my new OnlyCat- the cost is worth it! It’s easy to set up and use, one can monitor cat movements thought the day via the app and it is excellent at blocking contraband entry. The timer function makes it easy for cat guardians to control when which cats go out and in and my sleep quality and quality is much improved as a result. I also want to say a big thanks to OnlyCat for resolving a logistics issue regarding my flap efficiently, professionally and graciously even though an error was made at my end. I’m now saving up to get one for my mum and dad’s cat!

This cat flap is worth every penny

This cat flap is worth every penny. I can’t say I was bothered by the leaves, dead mice and rats, but the cat would also bring in live mice and rats and let them loose around the house. Now I can sleep in peace knowing there won’t be mice dying behind plaster boards, or be woken up by rats.

Game-Changer for Smart Cat Flaps – Highly Recommend!

This product is absolutely fantastic, and the creators should be incredibly proud of their work.

I previously used a SureFlap but decided to upgrade to the OnlyCat. Installation was effortless—it fit perfectly into the existing hole, taking no more than three minutes to set up.

One of the standout aspects of this product is the continuous rollout of new features and improvements. I initially encountered an issue with the cat flap, but after reaching out to the company, they sent me a replacement within 24 hours—exceptional customer service!

While the app is fairly basic, it provides all the essential features I need to monitor activity and set up rules. Given that they are nearing completion of their project backer commitments, I expect further enhancements over time.

Fortunately, my main troublemaker has been on his best behavior lately, so there haven’t been any surprise “deliveries.” However, I can see the AI in action, accurately assessing and granting access without issues.

I have no doubt that this product will only continue to improve, and I’m excited to see how this company grows in the future.

Life changing

I waited a while before writing this review to ensure it was accurate.

This product is absolutely amazing – it has given me my life back.
My cat was constantly bringing in live mice and dropping them in the house for me to catch. Where one might expect a cat to eliminate a rodent problem, mine was actively causing one!

The Onlycat cat flap has worked flawlessly since installation, thwarting every single attempt my cat has made to bring a mouse inside.

Another major benefit: switching from a smart cat flap that ran solely on batteries to one powered by mains has been a game-changer. It was a constant hassle to monitor battery levels on my previous unit, and a dead battery risked trapping my cat inside or out.
The Onlycat unit includes a battery backup, ensuring it continues working even if the power supply is interrupted.

In summary, I would highly recommend this to any cat owner, especially those dealing with a pet that brings in prey.
Every detail of the unit is well thought out and refined.

Absolutely superb product!

This product is fantastic! I installed mine a couple of weeks ago and today it’s just thwarted the first attempt (since installation) by my cat to bring a mouse inside. I heard the warning alert and was delighted to watch the video of her ‘contraband detected’ and cat flap firmly shut, denying entry! The OnlyCat team have been brilliant in providing regular updates throughout my waiting period (I backed the kickstarter and waited patiently for my turn in receiving the product), and the AI they have developed will keep improving/learning with more and more installations.
The team have been great, the product is superb, and my flat will now hopefully remain mouse and bird free! I love it.

A superb device

For two years our little Gus was regularly (sometimes three times in one night) bringing in live mice, then chasing them around the house. We would find ourselves strategically leaving tuppaware containers around the house to aid the quick capture of his prey. It got to the point that I’d struggle sleeping, waiting to hear the old cat flap go, fully expecting him to be bringing in more victims.
Since the installation of the onlycat flap in December we have not had one uninvited guest. It has correctly identified every single time that Gus has approached with contraband in his mouth. It is a fantastic product that has genuinely improved my sleep/life.
In addition the onlycat team has been on hand to aid with any questions I have had. Five stars just isn’t enough for this product/team. THANK YOU.

A life changing device!

This device has changed our lives!. We used to constantly worry about live mice, birds, rats, rabbits brought into the house and this cat flap has entirely eradicated the problem. The cats get confused at times wondering why they can’t enter with contraband, but are already used to it and we can leave them to enter and leave without worrying what we’ll return home to find. Not cheap, but 100% worth the cost

Worth Every Penny

Having waited nearly 2 years (invested when it started up) it arrived 2 weeks ago. Was really easy to install and connect to WiFi. Had to contact the team for a few pointers, but Tomas got back to me almost immediately every time and answered my queries. Yesterday the first contraband was detected and Coco the culprit was stopped from coming in. Lola has yet to try but I’m sure as spring approaches there’ll be many foiled attempts. Thank you Tomas & the team

Absolutely fantastic product which I'm…

Absolutely fantastic product which I’m thrilled with. Been waiting for it for a year and it is so worth every penny. It’s stopped so many mice being brought in and saved all the damage in the house they used to cause. Customer support is absolutely fantastic. I often find products aren’t as good as they advertise themselves to be but this really is. You can tell a lot of care and attention has gone into this product and it does exactly what it says. Highly recommend

Only Cat what a result.. It has taken him just over a week to start using it as he was too scared at the beginning with the bleeps and noises but yesterday 6 attempts to bring us the same present all foiled by you.. Thank you. I’m going to aske the question now of how much we value this cat flap and how much money in time and sleep we put on each prey not brought in.. For me half an hour at 3 in the morning chasing a mouse around the bedroom is worth £20-£30…. a clear up of debris and battle damage in the morning £5, it doesn’t take long to pay for itself in time and sleep…

Innovative and life changing. Our cat Luna had been bringing in mice and other prey every day over the course of a year which was causing us to be sleep deprived and constantly stressed. After some research online, to my luck, OnlyCat existed! We ordered instantly and honestly would have paid any sum of money to get this product. The onlycat is a genuine solution to what can be an extremely stressful problem.

The support at OnlyCat is also truly superb and deserves complete success and recognition for this product.

If you’re wondering if it’s worth it – Absolutely, even if your cat doesn’t bring in prey, it’s brilliant to know when they’re in and if other cats try to get in.

Would give more than 5 stars if I could.

I must say that i’m very enthusiastic about Only Cat! In the short period installed it already prevented a few times unwanted prey, so many thanks for bringing this product to market.
