Lower your field glasses, kill the engine of your jeep - there's a pair of cheetahs, male and female, under the acacia thornbush ahead.

This pair is probably having a mental battle over whether to remain in the cool shade or sprint across the searing plains, but the sighting of prey is surely a great temptation...
