I'm a big fan of the Science Diet brands...both my cats and my dogs are on a variety of these diets. They are expensive, but worth the extra money for the quality.
The company itself is also top grade. During this whole recall fiasco, they found out that they bought some wheat gluten from the same distribution company as some of the recalled Menu foods, so they pulled their diabetic food off the market just to be on the safe side, even though the people heading the recall said it was a bit paranoid to do so. Proves that Hill's isn't out to make that extra buck but cares for the pets instead....
