AI ANALYSIS
What MiauMiau's AI actually sees
This food is built on cereals and vegetable protein extracts, with chicken at only 5% and no whole meat in the top ingredients, making it fundamentally unsuitable as a primary diet for an obligate carnivore. The estimated carbohydrate load is very high at 40.6% on a dry matter basis, driven by grain and plant-protein fillers, while the DMB protein of 29.8% is marginal even for maintenance.
According to MiauMiau's analysis of over 5,000+ dry food products, Hill's Prescription Diet k/d + Mobility Cat Food scores below the dry food average.
