Though I don't tend to ever play up a cat's birth defects, like one eyed cats people say to name "Popeye", or three leggeds named "Tripod", I couldn't resist naming "Skippy" (in my siggy) that as he has a half a front leg from a birth defect. He was a very ill kitten when I rescued him 7 or so years ago, and was hospitalized with severe pneumonia. He survived it, though lost an eye during the ordeal. He does skip after me everywhere, so Skippy fits him purrfectly. My precious snaggle toothed vampire boy!
