Hill’s Pet Nutrition will reformulate its Science Diet dogs and cat foods to add more natural ingredients.

The company made the decision to reformulate the Science Diet petfoods because some consumers were making product choices based primarily on a set criteria for ingredients, rather than the overall promise of nutrition and clinical research. Hill's says the new Science Diet dog and cat food formulas will feature:

• Quality protein as the first ingredient
• Natural ingredients
• No chicken by-product
• No artificial colors or flavors
• Great taste, guaranteed

Along with the new formulation, Hill’s also will introduce new packaging designs, as well as new color-coded product groupings under Life Stage, Life Style and Life Care, which will soon appear in pet stores to make it easier for pet owners to select the right food for their pet. Hill’s will begin shipping the new petfood formulations to specialty pet stores and veterinarians in December.
