cheerleaders" (rabbits) were shown, as if these animals were on the sidelines. In 2011, the "bunny cheerleaders" were replaced by "chicken cheerleaders" (hens and roosters). The bunnies and chickens were replaced by five pigs in a "Piggy Pep Squad" in 2012. Hedgehog cheerleaders were introduced for 2013, and replaced with penguins in 2014. Also beginning in 2010, the American Animal Hospital Association (AAHA) began sponsoring the Puppy Bowl. A veterinarian was shown giving each puppy a physical prior to participation, provided care to any animal which might appear injured, and provided tips to viewers about proper animal care. Dr. Elisa Mazzaferro, Director of Emergency Services at Wheat Ridge Animal Hospital in Denver, Colorado, provided the official on-camera care for the puppies and other animals. A new element for 2011 was a parody of the popular "Kiss Cam" used at sporting events. The "Kiss Cam" returned from 2012 through 2020. Two other new elements were added in 2012: a cockatiel named Meep "tweeted" about the game from the sidelines (using the Twitter social media network), and Jill Rappaport, a TV reporter and animal advocate, provided color commentary. The hamsters in the blimp and Meep the "tweeting" cockatiel were retained for the 2013 show, but the piglet cheerleaders were replaced by baby hedgehogs in tutus. Owners of hedgehogs volunteered the use of their animals for the show. The tutus, however, did not stay on the animals. A new "Puppy Cam" (a miniature wide camera attached to a puppy's collar) was added in place of the "Kiss Cam", to provide viewers with a puppy's-eye-view of the action. A new feature in the 2013 game is the "Cute Cam," the slow-mo camera. Additionally, the human "stars" of Animal Planet's reality TV shows were added in 2013 as commentators. Another addition is a "special puppy hot tub" (a large pan of water) in which puppies will relax prior to or after their time on the field. For the 2014 edition of the Puppy Bowl, the tenth anniversary of the show, First Lady Michelle Obama opened the show with footage of puppies being "trained" for the Puppy Bowl on the South Lawn of the White House. Police dogs appeared on the field when the national anthem was played. Returning as the official "tweeter" of the show was Meep the cockatiel. The dwarf cat Lil Bub was added as a "commentator" broadcasting from a Chicago studio. In
