We reveal how many of our pets have been hiding incredible athletic abilities evolved from their wild origins. Discover ultra-running rodents who love working out on their wheels and the incredible distances they cover each day, the secrets of our guinea pig's remarkable turn of speed, the dogs who can outrun the most dedicated human athlete, and the cats agile enough to pick their way through a minefield of dominos, not to mention ballistic reptilian tongues, the weight lifting hamsters that can carry a quarter of their body weight in their cheeks and the bunnies leaping the equivalent of a double decker bus. Along the way we meet the chilled-out Tokyo tortoise who will outlive his owner by half a century, the Californian cat who loves to surf, the NYC rats visiting friends via a six-storey high wire act, and the extraordinary high-speed flight abilities of parrots, budgies and cockatiels. By celebrating, nurturing and unleashing our pets' extraordinary athletic talents we can bring joy and fun into their lives, as well as our own and strengthen the bonds between us.
