Green Fumo cat food can be distinguished by the label, cat food particles and taste. Genuine Green Fumo cat food is not made in China, so there will be two labels on the outer packaging bag. Authentic Green Fumo cat food will have a meaty aroma and the particle size is uniform. If it is a fake cat food, it may have an odor when you open the bag, and the quality control is not as strict as the authentic ones.
