Science Diet Mature Adult Indoor takes the top slot while Friskies Grillers' Blend comes in last among more than 250 dry cat food products rated by GoodGuide. Science Diet Adult Optimal Care Gourmet Turkey Entree Minced tops the list of more than 350 wet cat food products, with 9 Lives Chicken & Tuna Dinner finishing last.

Consumer Ally has teamed up with GoodGuide, whose experts have rated more than 65,000 consumer goods -- including food, toys, personal care and household products -- using factors that include concern for the environment, personal health and social responsibility, as consumers begin increasingly to consider those in addition to price.GoodGuide's ratings also include a brief explanation for each category, though the user can drill down into each score for more detail. The health score measures a product's potential health impact on consumers. The environment score is based on the impact of the product in question and the company's overall policies and practices. The society score evaluates social impact, which can include treatment of workers, workplace diversity, community involvement and corporate ethics.

As we wrote about on Friday, pet food is easily the most requested item by GoodGuide users, and the full ratings were published today, including methodology. Because GoodGuide rated both dry and wet food for cats and dogs, we've decided to publish two separate articles. You can read about the cat food ratings below, and the dog food ratings here.

GoodGuide rated 271 dry cat food products, which also included useful information for consumers on dry cat food. Below are its top-five best and worst products. In order to avoid repetition of a particular brand (Science Diet accounts for the top 19 dry cat foods, while Purina makes 9 of the 10 worst), we've skipped ahead to the next best or worst brand.
