Simon King, Jonathan Scott and Saba Douglas-Hamilton follow the lives of three cat families - lions, leopards and cheetahs - in Kenya's Masai Mara. Saba is on the trail of Bella the leopard, who has got rid of her overgrown son Chui and is being courted by all the male leopards in the area. Life's a battle for single mums Tamu the lion and Honey the cheetah. Keeping her four cubs fed means Honey must make some life-threatening decisions, while Tamu has to protect her family from a buffalo herd.
