Using this cat food is super easy. Just open the single - serve pouch and pour the food into your cat's bowl. You can serve it as a full meal or mix it with your cat's regular dry food as a topper. Remember to store any unopened pouches in a cool, dry place. Once opened, refrigerate the unused portion and use it within a day or two. Make sure to always provide fresh water for your cat. If your cat has any specific health conditions, it's a good idea to consult your vet before starting a new diet.
