To use this Purina Pro Plan cat food, simply open the can and serve it to your cat. You can feed it as a standalone meal or mix it with a small amount of dry food for variety. It's best to serve the food at room temperature for maximum flavor. Make sure to provide fresh water alongside the food. When it comes to storage, keep the unopened cans in a cool, dry place. Once opened, refrigerate the remaining food and use it within 2 - 3 days. Check the expiration date on the can before feeding. Also, if your cat has any specific health conditions or dietary restrictions, it's a good idea to consult your vet before making this food a regular part of their diet.
