AI ANALYSIS
What MiauMiau's AI actually sees
First ingredient is dried green peas (44%), a legume filler, and the primary protein sources are vegetable protein extracts and pea protein rather than animal tissue. The only named meat source is 4% duck as a by-product, making this a plant-protein-dominated formula inadequate for obligate carnivores.
According to MiauMiau's analysis of over 5,000+ dry food products, Hill's Prescription Diet d/d Dermatology scores below the dry food average.
