AI ANALYSIS
What MiauMiau's AI actually sees
The first ingredient is chicken by-product meal, an unnamed by-product, and the second ingredient is corn flour, a high-glycemic filler, which severely undermines ingredient quality. While the dry matter protein is adequate at 41.1%, the estimated carbohydrate load is very high at 38.8% due to the presence of corn flour, wheat gluten, corn protein meal, brewers rice, and wheat in the top ingredients.
According to MiauMiau's analysis of over 5,000+ dry food products, Royal Canin Fussy Adult Dry Cat Food scores below the dry food average.
