What MiauMiau's AI actually sees
First ingredient is a named organ meat (beef lung), but it is followed immediately by dehydrated poultry protein and soy flour, which is a plant protein filler. The as-fed protein is critically low at 5.0%, making the dry matter protein uncalculable but certainly far below 26%, and the formula relies heavily on soy flour, pea starch, and dehydrated peas as carbohydrate padding.
According to MiauMiau's analysis of over 5,000+ dry food products, Purina ONE Grain-Free Sterilised Beef scores close to the dry food average.
