What MiauMiau's AI actually sees
First ingredient is named poultry meal, but it is followed by multiple grains (rice, wheat, maize), with wheat as the third ingredient. Protein on a dry matter basis is low at 33.9%, and carbohydrates are high at 38%, signaling heavy filler use. No artificial additives are listed, which is a positive point.
According to MiauMiau's analysis of over 5,000+ dry food products, Royal Canin Regular Fit scores below the dry food average.
