To use this cat food, you can simply open the can and serve it directly to your cat. You can use it as a topper by sprinkling it over your cat's regular dry food to add flavor and nutrition, or serve it on its own as a full meal. After opening, if there's any food left, cover the can and store it in the fridge. Make sure to serve the refrigerated food at room temperature. Always provide fresh water for your cat when feeding this wet food. Check the expiration date on the can and keep the unopened cans in a cool, dry place.
