Royal Canin Gastrointestinal Fiber Response Dry Cat Food
Royal Canin Gastrointestinal Fiber Response is formulated to aid cats with digestive issues.  These issues can include acute or chronic constipation, fiber-responsive gastrointestinal disease, obstipation or megacolon.  A combination of highly digestible proteins and prebiotics help support digestive health.  EPA and DHA acids help protect against inflammatory responses within the GI tract.  A precise blend of antioxidants to help maintain a healthy immune system and to reduce DNA damage associated with cell aging.  This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.  GI Fiber Response is enriched with a blend of soluble and insoluble fibers to help reduce digestive problems such as diarrhea, constipation and hairballs.  Chelated minerals improve digestive and metabolic utilization of trace elements.
