AI ANALYSIS
What MiauMiau's AI actually sees
This diet is heavily plant-based, with vegetable derivatives and cereals as primary ingredients, resulting in low protein (28.9% DMB) and high carbohydrate content (43.9% estimated). While it avoids artificial additives, the ingredient quality is poor for an obligate carnivore, as protein comes largely from plant sources like maize gluten meal and pea protein, with only 5% tuna.
According to MiauMiau's analysis of over 5,000+ dry food products, Hill's Prescription Diet k/d Dry Cat Food with Tuna scores below the dry food average.
