To use this cat food, you can serve it straight from the pouch as a complete meal for your adult cat. If you prefer, you can also sprinkle it over your cat's dry kibble for an extra - tasty topping. Note that the product is going through packaging and formula changes, so you might receive either the new or old version. There's no special maintenance required; just keep it in a cool, dry place before opening. Once opened, cover the remaining food and refrigerate it, and use it within a couple of days.
