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.
Occasionally, the cat's body may use vomiting to clear the intestines of toxins. If the vomit contains excessive amounts of mucus, an inflamed intestine may be the cause. Undigested food in the vomit can be due to food poisoning, anxiety, or simply overeating.
