AI ANALYSIS
What MiauMiau's AI actually sees
First ingredient is chicken, but Brewers Rice and Corn Protein Meal in positions 2–3 indicate significant filler content. The food avoids artificial additives, but lacks transparency in protein density due to missing moisture data, and the heavy use of corn, wheat, and pea proteins suggests a high-carbohydrate, plant-protein-heavy formula.
According to MiauMiau's analysis of over 5,000+ dry food products, Hill's Prescription Diet Gastrointestinal Biome Stress with Chicken Cat Food scores below the dry food average.
