Feeding your cat this Purina Pro Plan dry cat food is easy. Just follow the feeding guidelines on the package based on your cat's age, weight, and activity level. Make sure to provide fresh water at all times. When you first introduce this food to your cat, do it gradually over a week or so. Start by mixing a small amount of the new food with your cat's old food and slowly increase the proportion of the new food. This helps prevent digestive upset. Store the food in a cool, dry place, and keep the bag tightly sealed after each use to maintain freshness. If your cat has any specific health concerns or dietary restrictions, it's a good idea to consult your veterinarian before making a switch.
