Purina ONE® Hairball Formula starts with your adult cat’s nutritional needs first to help support her optimal health, inside and out. With real chicken as the number one ingredient – and 0% fillers – all of our high-quality ingredients have a purpose. A natural fiber blend helps minimize hairballs while Omega-6 helps give your cat a radiant coat and healthy skin. The crunchy kibble helps reduce plaque build-up and whiten teeth. With 38g of protein per cup, it provides the protein your cat needs as a carnivore and helps support strong muscles, including a healthy heart. Purina ONE Hairball Formula is enriched with vitamins and minerals for strong bones and joints and is highly digestible so more nutrition goes to work inside your cat. Plus, it has a taste cats love.
