The World's Worst Cat-Hater
Chicago banker Rockwell Sayre must have been the worlds worst cat-hater. He lived in the early 1920's, and started a campaign to rid the entire world of cats by the year 1925. He offered financial rewards to cat killers.
He said that cats were "filthy and useless" and claimed to have inspired the killing of seven million cats during the first three months of his campaign. In 1925 he extended his campaign for a further ten years, as there were many cats still left. But soon after he himself died.
