Meerkat Manor is a British television programme produced by Oxford Scientific Films for Animal Planet International that premiered in September 2005 and ran for four series until its cancellation in August 2008. Blending more traditional animal documentary style footage with dramatic narration, the series told the story of the Whiskers, one of more than a dozen families of meerkats in the Kalahari Desert being studied as part of the Kalahari Meerkat Project, a long-term field study into the ecological causes and evolutionary consequences of the cooperative nature of meerkats. The original programme was narrated by Bill Nighy, with the narration redubbed by Mike Goldman for the Australian airings and Sean Astin for the American broadcasts. The fourth series, subtitled The Next Generation, saw Stockard Channing replacing Astin as the narrator in the American dubbing. Meerkat Manor premiered in the United Kingdom on 12 September 2005, and the first 13-episode series concluded on 24 October 2005. With the success of the programme in the United Kingdom, Animal Planet started broadcasting it on its national channels in Australia, Canada, and the US. It has since been rebroadcast in more than 160 other countries. The fourth, and final, series aired initially in the United States from 6 June 2008 to 22 August 2008; it aired in the United Kingdom in April 2009. In August 2009, it was reported that the programme had been cancelled.
