Residents in Boulder, Colorado, USA, lead the movement in feeding natural petfood diets to dogs and cats, according to an article from dailycamera.com.

Although the price of natural and organic petfoods can be more than traditional food, Boulder residents are willing to pay. Some pet owners attribute the higher-priced, premium-based foods to their pets' good health and lower veterinary bills. The movement toward natural petfoods may have started due to a major recall in 2007 involving nearly 100 petfood brands contaminated with wheat gluten and rice proteins, the article says.

"For people in Boulder, it's not about the money," said Marty Grosjean, owner of Only Natural Pet Store. "Boulder is on the cutting edge of everything."
