"We all know how finicky cats can be. Our particular cat has about 8-9 bags of dry food open at one time (spoiled cat!). We switch to different brands from time to time (wife says he wants variety in his food, like her!), but he genuinely seems to love his Science Diet - no question that our cat is definitely a Science Diet cat! Ocean Fish and Rice, Original, Hairball and Indoor are his SD choices. The other brands are for "variety," and not nearly as favorable. I understand that our cat is a Science Diet cat and yours may not be. Other foods he doesn't eat go to the shelter so as not to waste the purchase."
