Cows with good digestion have the guts to do anything. 
To launch Juice, the new Purina Nutrition Line created to help their digestion, we devised a campaign in which a cow, thanks to its good digestion, has the guts to do a very valiant thing: by exposing the perpetrator of a crime on the farm! 
The allegorical triumph of good not only restores harmony among the animals, but also makes the cow feel better.
