First of all, it's "Furry", not "Ferry". And "is", not "iz". Second of all, Caps lock is 5/16 of an inch next to your left pinky finger. Third, the question was already answered for you a handful of times in the thread, but since you're obviously not reading the thread, I'll post here for you again.
Furry is hentai where the characters are drawn as anthropomorphic animals, or bipedal, humanoid versions of the animal they represent. Picture a typical animal cartoon character, like Bugs Bunny, or Wile E. Coyote, or even video game characters like Fox McCloud, from the StarFox series.
