Whether it purrs, barks, hops or clops, Steve, Noel and Kate introduce viewers to a menagerie of animals, calling on the nation to find them the loving homes they deserve. They meet ex-shelter pets who've gone on to greatness, and help local would-be pet parents find their perfect playmate. Also tonight, Leona Lewis shares her love of giving shelter animals a second chance in life. For the next five nights, cats, dogs, rabbits, horses, parrots and pigs are seeking your help. So if Britain really is a nation of animal lovers, now's the time to prove it.
