Princess Pinot has been on Blue for some time and thrives on it. She eats the Chicken flavor of the dry with a spoonful of the canned mixed in (spa select variety, seafood flavors only, thank you very much). I feel the ingredients are far superior to many other brands and, believe you me, she is PICKY! Never had an issue changing over from Science Diet. As far as the cost; if you break it down, it's not that much money. We actually use half the food we did previously; the protein content fills up more that the unnecessary ingredients in other foods.
