Man's attitude to various animals changed many times in the course of centuries. From indifference or practicality, he went on to adoration and deification, and then to hatred. Ancient Egyptians, for example, highly appreciated the cat's ability to destroy rodents. The cat was much superior in this respect to the grass­snakes and weasels they had kept in their houses before. These proved unable to cope with hordes of rats which invaded Egypt from Asia. So the cat, a very useful animal, was ranked as a sacred animal and one of the most important animals, too. The goddess of the Moon, fertility and child­birth, Bast herself was portrayed by the Egyptians as a woman with a cat's head.

Sumptuous temples were built to this goddess, where cats were kept in luxury and fed the choicest of foods. They had their own priests and votaries, more numerous as a matter of fact than any other sacred animal could boast. According to the Greek historian Herodotus, the festival in the city of Bubastis, which had a temple dedicated to cats, was attended by as many as 700 thousand, who brought their offerings to the goddess in the shape of figurines of her made of gold, silver and bronze and adorned with precious stones.
