"Whole liquid milk from dairy cattle."
Raw whole milk carries protein, calcium, and fat — but most adult dogs and cats produce less lactase (the enzyme that digests milk sugar) as they age, the same way many adult humans do, so a meaningful share of pets get loose stool or gas from real dairy milk regardless of how it's processed into the final food. Not toxic, just not well-suited to the species drinking it. Score: 4/10.
A real but unresolved concern: often an ongoing FDA/AAFCO research question (like the grain-free/DCM investigation), a common allergen, or a vague-but-not-alarming label claim. -2.5 pts deducted.
