Asia - the most varied and extreme continent - stretching from the Arctic Circle to the equator. Walrus gather in huge numbers in the frozen north and brown bears roam remote Russian volcanoes. This is a world of the rarely seen, from yeti-like monkeys in the mountain forests of China to the most bizarre predator in the baking deserts of Iran. Asia is the largest of all continents but it seems there’s not enough space for wildlife. The deep jungles provide sanctuary for the last few Sumatran rhino.

In the first episode and for the first time ever, the programme compares the humble moggy with their big cat cousins, gaining surprising insights into the entire cat family. In Africa, lion whisperer Kevin Richardson proves how similar domestic pets are to the fearsome big cats and why there's more to feline communication than meets the eye. In the thick jungles of South East Asia, the series discovers which sabre-tooth wild cat has given tabbies their gravity defying climbing skills and in Namibia, shows how a strange looking cat called a caracal has given them the ability to jump over three metres and catch birds in flight, inspiring the phrase "put the cat amongst the pigeons". To truly understand the world’s most beloved purring pets, there needs to be an understanding of their wild relatives.
