How do I switch my pet from regular pet food to Hills Science Diet food?
You can start on Science Diet for your pet right away, but you have to make a gradual switch from the old food to the new. While making sure your pet’s total amount of daily food intake remains constant, mix increasing amounts of the new food with decreasing amounts of the previous food over a five-to-ten-day period. This should reduce the possibility of gastro-intestinal upset during a diet change.
