Hematemesis in Cats. Hematemesis, or the vomiting of blood, can affect a wide range of systems, depending on the source. The gastrointestinal system may be affected due to trauma, ulcer, inflammation, or the presence of a foreign object.
Swallowed blood, as from a nosebleed or forceful coughing, may cause bloody vomit, but truly vomiting blood usually represents something more serious and requires immediate medical attention. Bleeding in your upper gastrointestinal tract (mouth, esophagus, stomach and upper small intestine) from peptic (stomach or duodenal) ulcers or torn blood vessels is a common cause of vomiting blood. Call 911 or your local emergency number if vomiting blood causes dizziness after standing, rapid, shallow breathing or other signs of shock.
