A cat"s natural diet consists of high levels of protein and fat-and that"s what inspired this formula. We use whole grains, real chicken and other high-quality protein sources. We also include vitamins and minerals, a touch of leafy greens and fiber to help control hairballs. What didn"t we add? Artificial flavors or preservatives. --High in protein-like a cat"s natural diet--With whole grains and the goodness of leafy greens--A fiber blend helps control hairballs--No added artificial flavors or preservative
