Using this Inaba cat food is easy. Just open the cup and serve it to your cat. You can offer it as a main meal or as a delicious treat. It's best to serve it at room temperature to enhance the aroma and taste. Keep in mind that if your cat doesn't finish the whole cup at once, you can cover it and store it in the fridge for a short time, but make sure to use it within a day. There's no special maintenance needed for this product, just store it in a cool, dry place away from direct sunlight until you're ready to use it.
