AI ANALYSIS
What MiauMiau's AI actually sees
The food uses dehydrated poultry protein as its first ingredient, which is a concentrated protein source, but it is followed by multiple plant-based proteins and grains. The estimated carbohydrate content is 0.0% on a dry matter basis, which is highly suspect given the presence of barley and manioc as carbohydrate sources, suggesting an error in the provided DMB calculation for carbs.
According to MiauMiau's analysis of over 2,700+ dry food products, Royal Canin Diabetic scores close to the dry food average.
