S1, E1: The first episode looks at big cats in Africa and South East Asia. Lion whisperer Kevin Richardson proves how similar our pets are to the fearsome big cats and why there is more to feline communication than meets the eye. In the thick jungles of South East Asia, the sabre-tooth wild cat has given domestic tabbies their gravity-defying climbing skills, and in Namibia, a strange looking cat called a caracal has given them the ability to jump over three metres and catch birds in flight.
