AI ANALYSIS
What MiauMiau's AI actually sees
The first ingredient is 'Meat and animal by-products', an unnamed and low-quality protein source that signals rendered or slaughterhouse waste. The dry matter protein cannot be calculated because moisture is missing, but the as-fed value of 9% is so low that even best-case DMB protein is critically inadequate for an obligate carnivore.
According to MiauMiau's analysis of over 5,000+ dry food products, Hill's Prescription Diet Thyroid Care Y/d mit Huhn scores below the dry food average.
