Causes of blood in cat feces:

1. Internal parasites. When a cat is infected with internal parasites, the parasites cause irritation to the intestines, resulting in blood in the cat's feces.

2. Indigestion. Cats who eat too much or have unsuitable food are prone to indigestion. The color and smell of their poop are normal and have little impact, but occasionally there will be blood in their poop.

3. Drink less water. Cats drinking less water can cause dry stools, which can lead to anal rupture and bleeding.

4. Sick. When cats suffer from gastroenteritis, pancreatitis, or parvovirus, blood may appear in their feces due to gastrointestinal irritation.

5. Cat food problem. There is a problem with the quality of cat food. Problematic cat food will damage the gastrointestinal tract, resulting in blood in the stool, often accompanied by diarrhea.
