AI ANALYSIS
What MiauMiau's AI actually sees
This food is grain-heavy with corn as the first ingredient, leading to a high carbohydrate load (51.3% DMB) and low protein (32.6% DMB) unsuitable for obligate carnivores. While it contains joint-supporting supplements and natural preservatives, the reliance on plant proteins like wheat gluten and corn gluten meal, along with chicken by-product meal, significantly undermines its species-appropriateness.
According to MiauMiau's analysis of over 5,000+ dry food products, Royal Canin Feline Urinary SO® Aging 7+ + Calm scores below the dry food average.
