To use this Purina Pro Plan canned cat food, simply open the can and serve it to your adult cat. You can feed it as a standalone meal or mix it with a little dry cat food for added variety. Keep in mind that the can should be refrigerated after opening and consumed within a couple of days. Store unopened cans in a cool, dry place away from direct sunlight. Make sure to provide fresh water for your cat at all times. This food is formulated for adult cats, so it's not suitable for kittens. If your cat has any specific health conditions, it's always a good idea to consult your vet before making any changes to their diet.
