To use this Purina Pro Plan canned cat food, simply open the can and serve it to your cat. You can feed it directly from the can or transfer it to a cat bowl. It's best to serve at room temperature for maximum flavor. Make sure to provide fresh water alongside the food. Keep in mind that while this food is rich in nutrients, it should be part of a balanced diet for your cat. Store unopened cans in a cool, dry place. Once opened, cover the can and refrigerate any leftovers. Use the refrigerated leftovers within 24 - 48 hours to keep the food fresh and safe for your cat.
