    First Pet Food in Grocery with Real
    Chicken #1

    By making real chicken the #1 ingredient in Purina ONE®, we were the first pet food available in grocery stores to provide nutrition with a unique, super premium quality that wasn’t available for pets at the time.

    • Underweight
    • Ideal
    • Overweight

    Our Body Condition Score, a New Tool in the Fight Against Pet Obesity

    In our research, we were discovering the benefits of keeping a cat lean and healthy. But there wasn’t a simple way for people to determine if their cats were overweight. The solution? We developed a simple body condition score chart to help visually gauge a cat’s body condition. We also developed our feeding instructions to provide another tool for cat owners to help ensure their cat maintains a healthy weight.

    Targeted Nutrition Formulas Address Specific Needs

    As we did more research, we were finding different ingredient combinations beyond life stage specific formulations that could benefit certain types of cats. We released Indoor Advantage® and Sensitive Systems cat food to help owners to address the unique needs of their cat through nutrition, such as hairballs or sensitive skin and stomachs.

    Purina ONE® Introduces Wet Cat Food to Deliver Cats Protein-rich Meals

    With roots in arid climates, cats have evolved to derive much of their hydration from prey rather than drinking from sources of fresh water. Regularly feeding your cat wet food from Purina ONE® gives your cat a preferred source of energy and needed moisture.

    The True Nature of Cats

    A team of Purina experts journeyed to South Africa to study the African Wildcat, a wild ancestor to domestic cats. What they learned informed how enriched feeding experiences, purposeful play and stimulating environments each play a positive role in the life of your cat.

    SMARTBlend® Healthy Metabolism™: A Special Blend of Cat Food for Spayed or Neutered Cats

    When a cat is spayed or neutered, its body can undergo changes that can lead to a slowing metabolism. So we developed Healthy Metabolism™, a high-protein formula cat food with L-Carnitine to help these cats burn fat more efficiently and maintain a healthy weight.

    Retooling the Canning Process to Save Water and Materials

    By implementing an advanced cooling system in our production facility in St. Joseph, Missouri, we were able to cut water usage in the cooking and cooling process of canned wet foods by 30-40%. Since this process also used a gentler pressure cycle, we were able to use cans that are 0.0002 inches thinner. This translates to a savings of 265 tons aluminum per year.
