World Records for Pets and Other Animals

People are often drawn to the wild and wacky lists of various world records. Seeing pictures of the woman with the longest fingernails, or the man with biggest feet amuses just about everyone. Some people strive to be record-holders, and attempt to eat more cupcakes than anyone ever has in a single sitting, or to live in a tree for longer than anyone else. Animal lovers will be pleased to know that there are many different categories of world records that their favorite pets can compete in to set world records of their own. If nothing else, it is interesting to see what records animals have set.
