AI ANALYSIS
What MiauMiau's AI actually sees
The first and dominant ingredient in every recipe is a vague 'meat and animal by-products' blend, which severely limits protein source transparency and quality. While the dry matter protein is adequate at ~45% and carbohydrate content is moderate, the reliance on unspecified by-products as the primary ingredient is a critical weakness for an obligate carnivore.
According to MiauMiau's analysis of over 4,200+ dry food products, IAMS Naturally Adult Sea Collection scores close to the dry food average.
