To expand a bit on what was already posted here, in a broad sense, a member of the furry fandom is anyone who enjoys cartoons, art, stories, games or costumed play that involve anthropomorphic animals. Bugs Bunny fans, Teenage Mutant Ninja Turtles fans, Usagi Yolimbo fans, Starfox video game fans... If you like something that features animals that walk and act like people, you fit.
