Once your kitten is about a year old, you should begin to shift over to Precise® Feline Foundation Formula® for adult cats. Because our formulas are compatible, you won’t have any trouble getting your feline to eat her new food eagerly. Precise Feline Foundation Formula has the same high quality ingredients found in our kitten food. And the great taste comes from the best chicken meat meal, whole grain carbohydrates, pure chicken fat and natural chicken flavor.. And unlike some brands, there are no sugars or fillers. We’ve also added Ester-C® brand of Vitamin C supplement to our formulas to help strengthen your cat’s immune system. And, because ordinary minerals are not as easily absorbed, we use chelated minerals in our foods.
