Miscanthus grass is a non-GMO, perennial warm-season plant grown and harvested in the USA. It is one component of our exclusive P.B.F Prebiotic Balanced Fiber blend because it is an excellent source of fiber not commonly used in pet foods. Fiber is essential for a healthy digestive tract, and we utilize miscanthus grass to compliment our variety of fibers to achieve prebiotics in the gut. 
Grass also contains some nutrients for pets. You may have observed your dog or cat eating grass when they are outdoors or when it is available, in part because they simply enjoy it. Some will instinctually eat grass as a natural remedy to help soothe their stomach or aid in digestion.
