Cats

Revered as a god by the Pharaohs, the cat arrived in Britain with the Romans. But later it had to endure centuries of persecution and torture, a victim of its association with the old pagan religions. The cat had not changed - only people's perception of this solitary, promiscuous hunter of the night, whose light-reflective eyes and screeching voice were thought to be signs of the devil.

As the British Empire expanded, how did the world's cat population grow? What was its impact and how did cats transform society?
