Big Cats

Documentary following ultimate cat species from around the world, from the lions of Tanzania - the only cat species to live in groups - to the tiny rusty spotted cat of Sri Lanka, 200 times smaller than a lion but just as curious. The film also peeks into the secret lives of the Canada lynx, which lives further north than any cat, and follows an African leopard and mother, which for a decade has worn a radio collar allowing scientists to follow every twist and turn of her existence.

Advances in remote and low-light filming technology provides new insight into the secret life of the mysterious small cats. In South Africa, we follow the nocturnal pursuits of the tiny black-footed cat that stakes its claim to the title of the world's deadliest, and in remotest Mongolia we reveal the rarely seen Pallas's cat, at home with her kittens - she hunts by looking like a rock. Finally, in the Karoo of South Africa, we uncover the secret of the serval that thrives amongst the futuristic landscape of Africa's biggest industrial complex. These are remarkable cats, with surprising lives in extraordinary places.
