AI ANALYSIS
What MiauMiau's AI actually sees
This food uses pork by-products and chicken by-products as primary protein sources, which are lower quality for an obligate carnivore. The estimated carbohydrate content of 21.1% DMB is higher than ideal, and the presence of wheat flour and wheat gluten contributes to this. Carrageenan is also present as a thickener.
