More closely mimicking a carnivore's ancestral diet, Nutrience Grain Free offers all the same nutritious qualities of Nutrience Natural, but without the grain. Fresh meats and fish are combined with healthy fats, fruits, vegetables and botanicals, while grains are replaced with low-glycemic lentils and sweet potatoes. It's a great substitute for pets with certain food sensitivities, and an excellent choice for pets with a particularly active lifestyle or for pet owners who simply prefer to feed their pets a grain free diet.
