what is the normal color (range) for bowel movements
It depends on what your diet consists of
Light green stools—Too much sugar, fruits or vegetables and not enough grains or salt (or in the case of animals, too much grass)Mucous can reveal diverticulitis and gut inflammation due to allergies or parasites. Red or magenta stools-- ingestion of beets. Very dark stools: Too much red wine, too much salt in the diet, not enough vegetables. Blueberries, Pepto Bismol (the bismuth in it) and iron pills can also be responsible for dark stools. Pale or clay colored stools can mean that your gallbladder or liver is not working correctly.
