Background music in stores isn't new, but PetSmart has added a twist -- music for pets.

The pet retailer has commissioned Mood Media to provide background music not just in its stores, but also at its in-store PetsHotel boarding facilities to help reduce anxiety among dogs and cats being dropped off.

The decision to add music was based on feedback from "pet parents," said Shane McCall, VP-store design and visual merchandise for PetSmart, in a statement. "We're confident Mood's unique and customized music programs will further enhance the customer -- and pet -- experience," he said.

The system installed over the past 10 weeks encompasses 1,466 stores and allows for web-based management, including automatic scheduling of day parts and voice messages at the corporate, regional or store levels.

PetSmart will have what Mood calls "an upbeat playlist to create a fun, in-store retail experience" for shoppers, their "pet family members" and store employees. Pets at the PetsHotel will get a playlist heavy on "modern mellow tunes to create a calm atmosphere to help pets relax and enjoy their stay."

Mood Media and PetSmart declined to provide specifics of the playlists or the voice messages. But while it would seem Florence & The Machine's "Dog Days Are Over" might be a logical pick, Ted Nugent's "Cat Scratch Fever" and Duran Duran's "Hungry Like the Wolf" are probably out.
