Our read

Premium versus mass: Hill's Science Diet leads on a top nutrition score, brand trust, and a clearer label, while Iams ProActive answers with a lower sensitivity-risk profile and far better value, since Hill's price per 1,000 kcal sits near the bottom of the range we score. In our view Hill's takes it narrowly on the fundamentals.

This verdict is our opinion under the PetScored rubric, not veterinary advice. The exact sub-scores are in the table below; each food’s source confidence and limitations stay on its own scorecard.

Hill's Science Diet

Adult Indoor Chicken Recipe

Strong label transparency on calories, taurine, and feeding-trial substantiation. Weak spot is value: it prices like a premium dry food while leaning on wheat and corn structure after chicken.

Iams

ProActive Health Indoor Weight & Hairball Care Chicken & Turkey

An indoor weight-and-hairball kibble with chicken first and declared taurine, but a corn-heavy base (corn grits, corn gluten meal, whole corn) plus chicken by-product meal, powdered cellulose, and caramel color keep Ingredient Clarity low. The high fiber maximum is typical of the hairball positioning.
