Some cats may have a delicate stomach. That's why we recommend a gradual transition to Purina ONE for a successful start. Mix Purina ONE with your cat's current food progressively over a 7 to 10 day period.

This slow transition process will help your cat digest the carefully formulated ingredients and nutrients in Purina ONE by naturally adjusting the enzymes in her digestive tract.
