AI ANALYSIS
What MiauMiau's AI actually sees
First ingredient is a named meal (chicken and turkey meal), but it is followed immediately by wheat, broken rice, and maize, which are high-glycemic fillers. The dry-matter protein is only 33.6%, which is marginal for an obligate carnivore, and the estimated 40% carbohydrate content is driven by refined grains in the top five ingredients.
According to MiauMiau's analysis of over 5,000+ dry food products, Hill's Science Plan Senior Cat Food scores close to the dry food average.
