To use this cat food, simply serve it to your indoor cat aged 11 or older according to the feeding guidelines on the package. Make sure to provide fresh water at all times. When it comes to storage, keep the bag in a cool, dry place to maintain the food's freshness. As the product is going through a packaging change, don't be surprised if you get a new or old bag. Remember, this food is not for kittens, pregnant, or nursing cats. If your cat is in that situation, switch to the appropriate Hill’s Science Diet kitten food right away. Also, monitor your cat's weight and health, and adjust the feeding amount as needed to keep your furry friend in good shape.
