The House Rabbit Society stresses that rabbits should live indoors, and have at least four hours of quality running/playing time per day. This, in conjunction with a proper diet, will help keep your rabbit happy, healthy and affectionate for a lifetime. Perhaps the most important items in the rabbit diet that ensure good intestinal health are (1) adequate oral hydration and (2) adequate crude long fiber, which helps push hair and food through the intestines, and keeps the intestinal muscles well toned and moving quickly.
