Help! My cat is vomiting: 
Vomiting, or the forceful ejection of stomach and proximal duodenal (upper small intestinal) contents through the mouth, is a symptom commonly observed in cats; it is not a disease. Your cat’s vomiting can be a symptom of any one of a wide range of acute or chronic illnesses encompassing almost all body systems, from cardiovascular and respiratory to gastrointestinal to renal (kidney) to dermatologic. Differentiating vomiting from coughing and regurgitation is important.
When a cat is vomiting, you should see a considerable amount of abdominal movement. The cat's abdomen will seem to pulsate violently, and the cat's head might appear to bob.
Coughing involves the thorax rather than the abdomen. A cat that is coughing will often crane its head and neck forward, holding its head still while keeping its front paws under its chest and its elbows off to the side.
Regurgitation, or the passive expulsion of food or fluid from the oral cavity, pharyngeal cavity, or esophagus, usually is sudden, without the violent wind-up that proceeds vomiting. A regurgitating cat might be silent or could sound like it's gagging.
If your cat has recently been vomiting or vomits more than once a month, please consult with your veterinarian.
