To feed your adult cat, simply open the 5.5 oz can of Hill's Science Diet Adult Turkey & Liver Entree. You can serve it directly into your cat's bowl. Make sure to provide fresh water alongside the food. Remember, this food is only for adult cats aged 1 - 6. If your cat is a kitten, or pregnant or nursing, switch to the recommended kitten food. Store the unopened cans in a cool, dry place. Once opened, cover the remaining food and refrigerate it, and use it within a couple of days.
