Hill's Science Diet
A science-led brand with a deep, well-researched prescription range — clinically rigorous and consistent. Outside the therapeutic lines, though, the value is below average for the price: the standard panels lean on corn, grain and by-product meals rather than named single-source protein, and you carry a vet-clinic price premium for the brand and its shelf presence. The prescription range is the reason to buy it, not the everyday food.
