If you have a cat that's 10+, you'll read tons of articles that say they need more water/wet food. Dry food is harder on their kidneys (may be the liver. please verify for yourself). After a week on this food, his energy, mobility, and even how friendly he is took a serious uptick. Is it expensive, yes. Is it worth it, to me and my cat, absolutely.One minor note: the recommended serving size is 2 cans. We only give him 1 a day in conjunction with dry food.See full review
