To use this cat food, you can either serve a whole pouch as a complete meal for your adult cat aged 1 - 6 years or sprinkle it on top of their regular kibble. It's really easy to open the single - serve pouch and start feeding. Just keep in mind that this food is not for kittens, pregnant or nursing cats. Store the unopened pouches in a cool, dry place. Once opened, if there's any leftover food, cover it and keep it in the fridge. Use the leftovers within a day or two to keep it fresh and safe for your cat to eat.
