Most hair passes through the digestive tract easily, but large amounts of hair can lead to hairballs. That's why ROYAL CANIN Hairball Care in Gravy is designed to help eliminate ingested hair by stimulating the transit of intestinal passage - removing any excess hair that would normally remain in the stomach.
