AI ANALYSIS
What MiauMiau's AI actually sees
The first ingredient is a named poultry meal, but it is immediately followed by rice and vegetable protein isolate, signaling heavy plant-protein padding. Without moisture data, dry matter protein cannot be calculated accurately, and the presence of refined grains (maize, rice) in the top five ingredients points to a high carbohydrate load inappropriate for an obligate carnivore.
According to MiauMiau's analysis of over 5,000+ dry food products, Royal Canin British Shorthair Adult scores close to the dry food average.
