No chip. No collar. No add-on.
Compared with typical cat flaps, October 2026.
Sounds good. Will Flappie® fit your home?
Installation

Most people install Flappie® themselves in about 15 minutes with a screwdriver. For glass, a glazier or one of our partners does it.

What cat owners say
Our promise
We built Flappie for our own cat. And we know it isn't a small purchase. That's why you can test it at home for 30 days. If Flappie isn't right for you or your cat, just send it back.*
Denis and OliverFounders of Flappie
- 30-day returns
- 2-year warranty
- 5 years of free updates
«I've had the flap for about 6 months and was spared 41 "gifts"😉 in that time! The flap isn't cheap, but it's definitely worth every penny!! Thanks to the developers.»

Our story
Two brothers, one very determined cat
Denis and Oliver grew up with cats. When Dixie brought home one mouse too many, they built the flap you couldn't buy. Developed in Switzerland.
FAQ
Quick answers
Yes, with Cat ID. Flappie recognises your own cats by their looks and keeps other cats out, no microchip needed. Flappie collects the recordings automatically, and you assign them to your cats in the app (Flappie Labs). Collecting takes a few days to a few weeks depending on the cat, then Flappie prepares Cat ID. You can add new cats any time. Like any recognition, Cat ID can make mistakes, and it keeps getting better.
99% prey detection, day and night. The AI is trained continuously and gets better with every software update.
Not for prey detection: it runs on the device. You need Wi-Fi for clips and app control, to set up Cat ID, and for software updates.
The camera only films outwards, in front of the flap. Prey detection runs on the device. You'll find the clips in the app, and you decide which videos you share with others.
Yes. Premium adds more video storage and deeper insights into your cat's activity.
With the included 12 V power supply. Plan for a socket near the door.
Most people install Flappie themselves in about 15 minutes with a screwdriver. For glass, a glazier or one of our partners does it. Test Flappie and pair it with the app before you drill.
No. For a door or wall, get a quick OK from your landlord or property manager first. When you move out, the spot is restored. For a glass door, we fit Flappie into a new, made-to-measure pane, so your original pane is kept and simply goes back in when you move out. In a shared building, check briefly with the owners' association.
You have 30 days to change your mind*, in Switzerland too. In the EU, the 14-day statutory right of withdrawal also applies. Plus a 2-year warranty on the hardware.
*Our terms of service apply.
UK launch delivery is planned for the end of November 2026, with free shipping. Join the free waiting list to hear when orders open, in signup order. No payment is taken now; your Flappie is secured when you order and pay.
