Petfinder has announced the most popular dog and cat names from 2011. "Buddy" continues to dominant the doggy world for the fifth year in a row, and "Lucy" wins again for the first-choice cat name. The Twilight saga seems to influence both dog and cat owners, as the name "Bella" appears high on both lists. Does your pet's name appear on this list? Tell us your pet's name in the comments below!
