AI ANALYSIS
What MiauMiau's AI actually sees
First ingredient is whole Ocean Fish, but ingredient #2 is Brown Rice and #3 is Wheat Gluten, which demotes it; also uses Pea Protein, Brewers Rice, and Ground Pecan Shells as fiber filler. Protein dry matter basis is unknown because moisture/ash values are not given, so true protein adequacy cannot be verified and defaulted to ≤2.5; using a lower moisture assumption for dry food the DMB protein likely falls in the 37–41% range. The carb-heavy load from cereals and legumes (Brown Rice, Oats, Brewers Rice, Pea Protein) pushes the estimated DMB carbs well above 30%, making it filler-dense. Additive profile is relatively clean (natural preservatives only, no BHA/BHT) but the overall formula fails on top-ingredient protein source authenticity for an obligate carnivore kitten.
According to MiauMiau's analysis of over 5,000+ dry food products, Hill's Science Diet Kitten Ocean Fish & Brown Rice Recipe scores close to the dry food average.
