To use this cat food, simply open the can and serve it directly to your cat in a clean dish. You can feed it to your adult cat as a regular meal. Keep in mind that different cats may have different appetites, so adjust the amount according to your cat's needs. When it comes to storage, keep 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. Also, always make sure your cat has access to fresh water. If your cat has any special dietary requirements or health issues, it's a good idea to consult your vet before starting this food.
