Hematochezia (Blood in Stool) in Cats

Cats

Overview of Feline Hematochezia (Blood in Stool)

Hematochezia is the presence of bright red, fresh blood in the feces in cats. Hematochezia usually occurs with bleeding in the lower intestines (colon, rectum). Hematochezia should not be confused with melena , which is the passage of dark, tarry, black feces. Melena represents the passage of old, digested blood that has occurred with bleeding higher up in the intestinal tract.

Below is an overview of Hematochezia (Blood in Stool) in Cats followed in-depth information about the causes, diagnosis and treatment of this condition. 

In cats, the presence of hematochezia may be a symptom of either a minor problem, or a potentially more serious problem in the animal. One occurrence of hematochezia may be a minor and transient event. Repeated or persistent hematochezia is more serious and should not be ignored. There are several possible causes. The most common cause in older pets is cancer and in younger pets are parasites.

General causes include:
