Remember, changes in your cat’s diet should be made gradually to allow your cat to become accustomed to a new food. Substitute small amounts of the new food for the old food, gradually increasing the amount of the new food while decreasing the old food, over a period of 7 - 10 days. This gradual transition will help avoid dietary upsets—something both you and your cat can appreciate. Provide adequate fresh water in a clean container daily. For your pet’s health, see your veterinarian regularly. .
