To use this Tiki Cat Aloha Friends canned cat food, simply open the can and serve it to your cat. You can offer it as a standalone meal or mix it with other cat food. Keep in mind that it's best to feed according to your cat's age, weight, and activity level. After opening, store the remaining food in the fridge and use it within a day or two. Also, always provide fresh water for your cat. No special maintenance is required for the canned food itself, just make sure to store it in a cool, dry place before opening.
