Cat bringing you gifts?

Your cat will typically hunt 110 animals per year, and bring of 18% them home. This means cleaning up animals remnants in your home, in the middle of the night. OnlyCat® changes this.

OnlyCat® detects prey

Advanced AI vision technology detects the presence of prey. OnlyCat® can detect mice, birds, rabbits, rats, squirrels, and other animals large enough to be seen by the camera.

OnlyCat® locks

Within a fraction of a second OnlyCat® detects the prey and temporarily locks the cat flap.

OnlyCat® lets you know

OnlyCat® connects to your Wi-Fi, and sends you short video clips of your cat's transits. You'll feel more connected to your cat, and you'll receive a critical alert whenever a prey delivery attempt is foiled.

Frequently Asked Questions

OnlyCat will stop my cat bringing home a mouse. What about other prey?

OnlyCat® will prevent entry with most prey if it is visible to the camera. Over time, it will learn from examples it sees. This includes: mice, birds, slow worms, rats, rabbits, squirrels, snakes, frogs, pheasants, bats, voles, shrews, weasels... the list goes on!

Can OnlyCat stop other cats entering my home?

OnlyCat® smart cat flap features microchip recognition as well as prey-detection, giving you full flexibility to choose which cats can enter and exit.

You can keep rival cats out, and even set day and time-based rules!

How accurate is the prey recognition?

Our first prototype has been in use for over 12-months and we achieved 100% detection accuracy within the first few weeks. We believe 99%+ accuracy should be achievable for everyone. Upon launch, accuracy should be high, and if there are any detection errors, these can be quickly reported helping the system learn.

Isn't OnlyCat® too expensive for a cat flap?

OnlyCat is the most advanced cat flap on the market - packed with state-of-the-art smart technology. With OnlyCat® you're not just buying a cat flap - you're buying peace of mind. You can sleep, work, and travel without worrying about what the cat drags in. With the video timeline and push notifications you'll feel more connected to your cat than ever before. You'll wonder how you ever lived without it.
