Iams petfood brand has launched its Unconditional Love Tails contest, which asks pet lovers to tell the story of the unique bond shared with their pets for the chance to win a cash prize, free Iams petfood and more.

Now through March 3, consumers can go to Iams' Facebook page to enter the contest and submit a story and photo about the unique bond they share with their dogs and cats.

Iams will select 10 finalists to win a cash prize and a year's supply of petfood. A grand-prize winner will also be chosen among the finalists by Facebook fans to appear with their pet in a national advertisement for Iams.
