The American Pet Products Association (APPA) has a lot to bark, meow, and crow about. The group is a not-for-profit trade organization that comprises more than 1,000 pet products manufacturers and importers. The APPA promotes pet ownership and pet products and monitors legislation and regulation and responds to both. It also provides its members with services such as market and scientific research. The group's annual Pet Products Trade Show is the largest of its kind. In 2009 APPA teamed up with Pet Industry Distributors Association to host the first annual Global Pet Expo. The group was founded in 1958 as the American Pet Products Manufacturers Association.
