AI ANALYSIS
What MiauMiau's AI actually sees
First ingredient is a named meal (dehydrated poultry proteins), but it is followed by rice, maize, and wheat, indicating heavy grain filler. Protein is only 30% as-fed with no moisture given, so dry matter protein is likely marginal for a carnivore, and estimated carbs exceed 30% DMB. Positively, the formula contains no artificial preservatives, colors, or added sugars, and includes beneficial additions like fish oil and glucosamine.
According to MiauMiau's analysis of over 5,000+ dry food products, Royal Canin Outdoor scores close to the dry food average.
