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.
Diet Change. Sometimes cat vomiting is caused by a rapid change in their diet. If you have recently switched from wet cat food to dry cat food, for example, this could cause your cat to vomit. Try going back to the previous food, and re-introducing the new food on a gradual basis.
