Purina ONE® Indoor Advantage starts with your adult cat's nutritional needs first to help support her optimal health, inside and out. With real turkey as the number one ingredient – and 0% fillers – all of our high-quality ingredients have a purpose. This formula contains a natural fiber blend to help minimize hairballs and promote healthy digestion. It also contains 10% fewer calories than Purina ONE Salmon & Tuna Flavor to help support a healthy weight. Omega-6 helps give your cat a radiant coat and healthy skin while the crunchy kibble helps reduce plaque build-up and whiten teeth. With 42g 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 Indoor Advantage is enriched with vitamins and minerals for strong bones and joints. Plus, it has a taste cats love.
