It may be a problem with diet or a disease such as dysentery or intestinal obstruction. If the stool is dark yellow, it is more common in hemolytic jaundice, that is, the yellow biliary produced by the massive destruction of red blood cells. Often accompanied by hemolytic anemia, if the stool is black stool (because black as the tar on the road, also known as tar-like stool), common in gastrointestinal bleeding stool. However, excessive consumption of meat, animal blood, liver, spinach, oral iron, tincture, activated carbon, etc., stool can also be black, should be distinguished.

1 occult blood test: a small amount of bleeding in the digestive tract, red blood cells are destroyed and destroyed and can not be found under the microscope, it is called occult blood (OB), and now it is detected by a specific high reverse passive hemagglutination method. OB is positive, even strong positive. However, this test should exclude false positives caused by food or drug factors. If necessary, the animal's internal organs, blood, lean meat and green leafy vegetables can be fasted for 3 days.

2 Qualitative test of sessile biliary: check for the presence of feline (also known as urinary bilirubin) in the feces. Fecal bilirubin can be combined with mercury to form a red compound, and the depth of red is proportional to the cetilin content. Hemophilic anemia is strongly positive, and the common bile duct obstruction is negative (not red).
