Natural Balance® Ultra Premium Pet Formulas are made for All Life Stages and provides premium nutrition for every stage of life. In Nature, your pets would not have the choice of puppy or kitten formulas, nor lighter formulas for their senior years; they would simply live on a diet of mostly meat and and some grain. In a natural free environment, animals instinctively eat more or less, depending on their age and activity level.
