National Cat Lovers’ Month has no documented creator and no primary establishment record. It is a grassroots December observance promoted by animal-welfare organizations, veterinary practices, and pet-care brands rather than declared by any single founder, government, or company.
Egypt made the cat sacred
In ancient Egypt the cat crossed from useful to holy. Cats were tied to the goddess Bastet, whose cult center was the city of Bubastis, and the devotion left a physical record. Excavations at Beni Hasan in the late 1880s uncovered an animal cemetery, most of it cats, offered to that cult.
The reverence carried real penalties. The historian Diodorus Siculus recorded that around 60 BC an Egyptian crowd killed a Roman for killing a cat, even as the pharaoh tried to step in and stop them.
