AI ANALYSIS
What MiauMiau's AI actually sees
This food relies on chicken and turkey meal as primary protein sources, but the second and third ingredients are maize and broken rice, which are high-glycemic fillers inappropriate for obligate carnivores. With 39.3% estimated carbohydrates on a dry matter basis and only 33.7% DMB protein, it is far too plant-heavy and protein-poor to support feline metabolic health.
According to MiauMiau's analysis of over 5,000+ dry food products, Hill's Science Plan Sterilised Mature Adult Cat Food scores below the dry food average.
