AI ANALYSIS
What MiauMiau's AI actually sees
Pork liver as the first named meat offers beneficial organ nutrients, but the inclusion of pork by-products and corn flour quickly lowers ingredient quality. The dry-matter protein (33.3%) meets only minimal carnivore needs and estimated carbs are high at 31.1%, with refined corn and guar gum further detracting from an optimal feline diet.
According to MiauMiau's analysis of over 5,000+ wet food products, Hill's Prescription Diet y/d with Chicken Wet Cat Food scores below the wet food average.
