The composition is appropriate for the price, so you shouldn't expect too much. However, what is missing from almost ALL Purina "ONE" series is the information on the phosphorus, calcium, and magnesium content in the food. If Purina is hiding these values, I assume they are too high, which is disastrous for a urinary product that is supposed to prevent or at least not promote struvite stones.
