Big Cat Diary, also known as Big Cat Week or Big Cat Live, is a long-running nature documentary series on BBC television which follows the lives of African big cats in Kenya's Maasai Mara. The first series, broadcast on BBC One in 1996, was developed and jointly produced by Keith Scholey, who would go on to become Head of the BBC's Natural History Unit. Eight further series have followed, most recently Big Cat Live, a live broadcast from the Mara in 2008. The original presenters, Jonathan Scott and Simon King, were joined by Saba Douglas-Hamilton from 2002 onwards. Kate Silverton and Jackson Looseyia were added to the presenting team for Big Cat Live.
