AI ANALYSIS
What MiauMiau's AI actually sees
While chicken is the first ingredient, the immediate presence of corn gluten meal and wheat gluten significantly dilutes the protein quality. The high estimated carbohydrate content due to corn, wheat, and barley makes this food unsuitable for an obligate carnivore's primary diet.
According to MiauMiau's analysis of over 2,700+ dry food products, Hill's Prescription Diet ONC Care with Chicken Dry Cat Food scores close to the dry food average.
