Wild outside. Calm inside. Your cat comes and goes. OnlyCat watches the door — you don't have to. The flap sees every arrival, recognises every cat, and when someone tries to bring home a "gift" — a mouse, a bird, whatever tried its luck — the door quietly says no. You sleep through the night. You leave the house. The hallway stays clean. And every morning you can see exactly what happened while you weren't looking. PROTECT THE HOME • Prey detection stops contraband at the threshold — the flap simply doesn't open. • Review the evidence later: every event on video, from routine transits to heroically thwarted deliveries. • Contraband detected. Crisis averted. FREEDOM FOR THEM • No collars, no compromises: recognises your cats by their microchips. • Rules per cat: who may go out, who may come in — and when. • Unlimited cats per device — harmony for the whole household. BRING THEM HOME SAFE • Night curfews bring wanderers home before dark — set once, forgotten. • Who's in and who's out, at a glance. • Real-time notifications for arrivals, exits and attempted smuggling. THE APP • A live activity feed with video of every coming and going. • A profile for every cat: habits, daily rhythms, prey attempts. • Remote unlock, door policies and curfews — control from the sofa. • Share the clips. "Nice try, Mabel." Works with your OnlyCat® flap. Set up in minutes. Stay connected. Feel relieved. Let cats be cats.
