Got pets? According to the latest pet owners survey from the American Pet Products Association (APPA), 62 percent of U.S. households do. Despite the down economy, Americans continue to spend money on their pets, an estimated $50.84 billion this year alone, according APPA. Pet owners are discovering products like carpet tiles from iCarpetiles.com, an affordable DIY flooring product that’s easy to install, clean or replace – especially since accidents, spills and dirt come with the territory.
