Who says only human kids can have all the fun on Halloween? That's the thinking behind PetSmart's new Monster Cute Photo Contest, which comes with a pretty wicked grand prize: a cameo in a PetSmart commercial. All you need is a camera, a fabulous costume and a pet who can strike a spooky pose.

The Costumes

A recent PetSmart survey found that 17 percent of people plan to dress up their pets for Halloween — and the store has stocked plenty of ghoulish getups for the occasion from Top Paw and Whisker City. There's also a collection from Martha Stewart, who's dreamt up a dragon, a silver-winged devil and a fetching dracula.

The Contest

Whether you’ve crafted something creepy from scratch or snatched up a costume at the store, you can submit a picture of your little monster in Halloween garb to PetSmart’s "Monster Cute Photo Contest," in conjunction with Greenies®, on PetSmart's Facebook page.

PetSmart will announce the 25 finalists on Halloween, and voting for the grand prize winner will go through November 3. The top monster will appear in a PetSmart TV commercial — and get $1,000 round-trip airfare to the commercial shoot (that's for the winner, pet parent and a guest) and a one-year supply of Canine Greenies® Dental Chews or Feline Greenies® Dental Chews.

In-Store Fun This Saturday

You can also bring your furry trick-or-treater to PetSmart’s annual, in-store Howl-O-Ween Costume Contest on Saturday, October 22, from 3 P.M. to 5 P.M. Three winners will be named at each store. The treat: a voucher good for Greenies, Toy Shoppe® or Grreat Choice™ dog and cat toys!
