Overview: A look back at the finest moments of the series in which two brave individuals volunteered to experience life as an animal for four long days. The contributors tell the story of their experiences, as we discover what these modern day Dr Doolittles really learned about the animals they shared a home with, how they coped with the food they had to eat, what it's like to wallow like a pig, defend your food from hungry foxhounds, swim like a seal, mate like a penguin and be kicked by a horse. Has the experience made them re-evaluate their own lives and what has changed for them now they are back in the human world?
