AI ANALYSIS
What MiauMiau's AI actually sees
The first ingredient is chicken by-product meal, and the formula is loaded with high-carb fillers like brewers rice, corn, and wheat, pushing estimated carbs to 46.2% on a dry matter basis. It uses natural preservatives and lacks artificial colors or harmful additives, but the overall ingredient quality and macronutrient balance are poor for an obligate carnivore.
