AI ANALYSIS
What MiauMiau's AI actually sees
The first ingredient is whole salmon (17%), but it is immediately followed by dehydrated poultry protein and wheat, with corn and soy flour also in the top five, dragging down ingredient quality. Dry matter protein cannot be precisely calculated due to missing moisture data, but even an optimistic estimate lands around 38-40%, which is below the ideal for obligate carnivores; meanwhile, wheat, corn, and soy dominate the carbohydrate padding, placing refined grains prominently in the top three ingredients.
According to MiauMiau's analysis of over 5,000+ dry food products, Purina ONE Adult Beef Whole Grain scores close to the dry food average.
