"The inorganic mineral residue remaining after a food is incinerated."
High ash content in cat food is associated with urinary tract crystals and stones. Low-ash diets are often recommended for cats with urinary issues. Ash is not added — it's the natural mineral content of the ingredients. High ash usually means low-quality protein sources with lots of bone.
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.
