Nestlé Purina PetCare is the pet food division of Swiss based Nestlé, following a merger in 2002 between the Nestlé's Friskies PetCare Company and the American Ralston Purina Company.Purina traces its roots back to 1894, when founder William H. Danforth began producing feed for various farm animals under the name Purina Mills. Later, in 1902, he merged with health guru and visionary Webster Edgerly, founder of Ralstonism, who was at the time producing breakfast cereals, to form the "Ralston-Purina Company".
