Cambyses II had only recently conquered Egypt at the Battle of Pelusium by using the Egyptian’s own beliefs against them. Knowing their veneration for animals generally, and the cat in particular, he had his soldiers round up as many stray animals as possible and paint the image of the Egyptian cat goddess Bastet on their shields. He then marched on Pelusium, driving the animals before his forces and demanded the city’s immediate surrender. The Egyptians complied rather than risk hurting the animals and enraging Bastet. link
