Also known as emesis, vomiting is a common complaint seen in cats that is defined as the ejection of the contents of the stomach through the mouth. Regurgitating is often diagnosed as vomiting. Food which is regurgitated comes from the esophageus shortly after it has been consumed & contains non-digested food. Regurgitating does not involve heaving prior to expulsion, nor will it contain digested food or bile which is often seen with true vomiting.

Vomiting is the forceful ejection of food from the stomach & upper intestine. The cat salivates, appears to attempt to swallow, wretches, abdominal muscle contractions can be seen & the cat will retch, make a gagging sound & produce vomit. Vomit will often contain bile, blood & mucus.
