Although you'll be anxious to see the difference Purina ONE can make in your cat, please allow 7-10 days to ease the transition from your cat's current food. Each day, simply feed a little less of the previous food and a little more Purina ONE until you're feeding Purina ONE exclusively. This gradual transition will help avoid dietary upsets.
