Artificial coloring is used in some pet food to give it a more desirable and consistent appearance or to differentiate between flavors in the same product. The quality, digestibility and nutrition of the product is unaffected by the use of artificial coloring. Some colors are derived from natural sources, such as beet powder and turmeric. Small amounts of dyes are used to produce the color.The dyes commonly used in Purina® formulas have been recognized as safe by the FDA for use in both human foods and pet foods.1Independent reviews and studies show that dyes are not responsible for food allergies in dogs and cats.2,3Purina has a long history of producing high-quality, highly nutritious pet foods that are rigorously tested.
