AI ANALYSIS
What MiauMiau's AI actually sees
First three ingredients are plant proteins (wheat gluten, corn protein meal, soya meal), offering poor protein quality for an obligate carnivore. Added sugar (xylose) and flavor enhancer (digest) are adverse, and the ingredient list is heavy in low-value grains/legumes with uncertain moisture masking true dry matter protein adequacy.
According to MiauMiau's analysis of over 5,000+ dry food products, Purina Pro Plan Veterinary Diets Feline OM ST/OX - Obesity Management scores below the dry food average.
