AI ANALYSIS
What MiauMiau's AI actually sees
The first ingredients are unnamed 'poultry by-products' and 'pork by-products', which are low-quality, non-specific protein sources that would score a 2.0, but the inclusion of 'corn starch mixture' as the third ingredient, a pure filler, further degrades the ingredient quality. The dry matter protein is excellent at 54.4%, but this is undermined by the heavy reliance on by-products and the presence of corn starch and powdered cellulose as fillers.
According to MiauMiau's analysis of over 5,000+ wet food products, Royal Canin Urinary S/o Adult Wet Cat Food in Loaf scores close to the wet food average.
