These changes in the formula of pet food products can happen due to a large number of reasons. Some of these reasons can include but are not limited to changes in the quality of the ingredients, unavailability of certain ingredients, the discovery of better ingredients for the formula, increase in the initial cost of the ingredients, the discovery of certain negative effects of one or more ingredients, and availability of better product formulation by the competitors on the same price range and with similar function.
