Killing Kittens is the best-known members' party brand built on female sexual empowerment — celebrating, by its own count, twenty years of it. The premise has not changed since the beginning: every Killing Kittens party is designed as an immersive experience of fantasy and exploration in which the women — the Kittens, in house language — are firmly in control every step of the way.

That principle shapes the mechanics. Membership is vetted and runs through the brand's own app, parties prioritise the safety and pleasure of Kitten members by explicit policy, and the brand frames its work as a challenge to established gender stereotypes. It is among the most press-covered names in this world, with features across Cosmopolitan, Glamour, The Guardian, the BBC and Playboy.

London is home turf, with a regular calendar of parties; New York carries its own programme, and the KK Cruise takes the format to the Mediterranean — recent itineraries calling at Barcelona, Monte Carlo, Florence, Portofino and Marseille. Venues are revealed to members, in the private-party tradition.

Membership, party calendars and applications run through the brand's own site and app. Browse our London guide for the city's other members' parties and venues.
