Using this Purina Pro Plan cat food is super easy. Just open the can and serve it in your cat's dish. You can feed it as a standalone meal or mix it with dry cat food for a different texture. Make sure to provide fresh water for your cat at all times. When it comes to storage, keep the unopened cans in a cool, dry place. Once opened, cover the remaining food and refrigerate it. Use the refrigerated food within 2 - 3 days. If your cat has any special dietary needs or health issues, it's always a good idea to consult your vet before starting a new food. And remember, every cat is unique, so adjust the serving size according to your cat's age, weight, and activity level.
