8 out of 10 Cats is a television comedy panel game made by Zeppotron (a subsidiary of Endemol) for Channel 4. It was first broadcast on 3 June 2005. The show's title is derived from a well-known advertising tagline for Whiskas cat food which originally claimed that "8 out of 10 Cats prefer Whiskas". The show is based on opinion polls, and draws on polls produced by a variety of organisations and new polls commissioned for the programme carried out by company Harris Poll.
