PetSmart is gearing up for its highly-anticipated, sixth-annual Halloween photo contest, and this year one lucky pet will win a chance at stardom with an appearance in a national PetSmart television commercial that will air in 2011.

This year’s theme is “Scare Your Way into a PetSmart Commercial,” and the contest kicks off Monday, September 13.

Pet parents can enter by visiting www.facebook.com/PetSmart and uploading a photo of their pet decked out in their Halloween best. Facebook fans, pet parents and their family and friends will vote for the winner, who will be announced on November 1. PetSmart is also giving away more than $3,600 in cash prizes and gift cards to those who participate!
