This class includes production of prepared pet foods: preparations consisting of mixtures of materials or of materials specially treated or packaged to make them suitable as feed for dogs, cats, birds, fish or other pet animals.

Manufacture of prepared feeds chiefly for farm animals including pre-mixes or feed concentrates, sweetened forage or feed supplements.

Exclusions: Production of fishmeal for animal feed is classified in class 1512 (Processing and preserving of fish and fish products).
