OnlyCat AI Cat Flap — Supplied & Fitted
OnlyCat is the world's first AI cat flap with prey detection — an on-device camera and computer-vision model stop your cat bringing mice, birds and other "gifts" through the door. We're UK installers for OnlyCat, fitting it into glass patio doors, uPVC doors, composite and wooden doors across the North West, Cheshire, Staffordshire, Yorkshire and North Wales.
Why Choose OnlyCat?
Traditional microchip cat flaps solve one problem — they stop strays coming in. OnlyCat solves a completely different one: it stops your own cat bringing prey into the house. If you've woken up to a live mouse on the landing or a half-eaten bird on the kitchen floor, you already know why this matters. OnlyCat uses a small integrated camera and an on-device AI model to recognise prey in your cat's mouth and keep the flap physically locked until they drop it.
It also works as a smart camera flap. Every entry is captured as a short clip, and you get a push notification on the OnlyCat app whenever an unknown cat approaches or your cat is refused entry. Because the AI runs locally on the device, entry decisions are near-instant and your cat's photos never need to leave your home.
- On-device AI prey detection — the only cat flap that does this
- Camera-based cat recognition (no microchip required)
- Push notifications with photos for every entry attempt
- Blocks unknown cats automatically
- Rechargeable battery — several weeks per charge
- Wi-Fi connected for notifications & AI model updates
- Direct-from-manufacturer warranty (registered to you)
- Fits standard cat flap apertures — no bigger cut-out needed
How Prey Detection Works
Camera Captures Approach
A short video clip is recorded every time any cat approaches the flap from outside.
AI Analyses Each Frame
An on-device model checks whether it's your cat and whether they're carrying prey in their mouth.
Flap Decides & Notifies
If prey is detected, the flap stays locked and you get a photo notification. No prey — instant entry.
Wi-Fi for Updates
Your home Wi-Fi is used only for notifications and AI updates. The flap keeps working if internet drops.

Fitting OnlyCat Into Your Door
OnlyCat has similar physical dimensions to a standard microchip cat flap, so it fits in every common door type. Here's what's involved:
Glass Patio & French Doors
We replace one glass panel with a new toughened safety glass unit, pre-cut with the OnlyCat aperture. Your existing frame stays in place. Most popular install — around 60% of our jobs.
Typical install time: 1–2 hours
Learn more →uPVC Doors
We route directly into the uPVC panel using tools designed not to crack the plastic. The OnlyCat mounting sits flush in the cut-out. Suitable for single and multi-point locking uPVC doors.
Typical install time: 45–90 minutes
Learn more →Composite Doors
Composite doors have foam-filled cores between GRP skins. We use a plunge-cut technique for a clean aperture without damaging surrounding structure.
Typical install time: 45–90 minutes
Learn more →Windows & Wooden Doors
Window installs use a replacement glass unit; wooden doors are the simplest of all — a jigsaw aperture with sealed edges takes under an hour.
Typical install time: 30–90 minutes
