Using Purina Cat Chow Complete dry cat food is easy. Just serve it in your cat's bowl according to the feeding guidelines on the package. These guidelines take into account your cat's age, weight, and activity level. Make sure your cat always has access to fresh water when eating this dry food. When storing the food, keep it in a cool, dry place and seal the bag tightly after each use to maintain freshness. If you're switching your cat from another food to this one, do it gradually over 7 - 10 days by mixing increasing amounts of Cat Chow Complete with the old food. This helps prevent any digestive upset. Keep an eye on your cat's weight and adjust the feeding amount as needed to ensure they stay healthy and happy.
