Talk about rags to riches. Until January, Larry was a stray tomcat roughing it on the streets of London. But shortly after a London animal shelter rescued him, a delegation from No. 10 Downing Street selected the four-year old kitty to hunt down mice in the offices and meeting rooms of the Prime Minister. Despite sleeping through the first 45 minutes of his press photo call on February 15, Larry has wasted little time cozying up to Britain's most powerful politician. According to his former keeper, "They got on famously. There are cat hairs all over David Cameron's nice suit." If the cat can keep up the charm offensive, he may earn some rat-a-touille alongside all the rat.
