Stomach

After exiting the esophagus, food enters the stomach to begin the digestive process. The stomach mechanically and chemically separates food into smaller pieces prior to entry into the small intestine. Vomiting is a hallmark sign of stomach irritation. Overeating behaviors and dietary intolerance commonly result in vomiting. Curious cats may inadvertently ingest string or small toys that become lodged in the stomach. Vomiting may also be caused by factors outside the intestinal tract, including kidney and liver disease, toxicities, and hormonal imbalances (e.g.: hyperthyroidism). Lab work and abdominal x-rays help to identify the underlying cause of the stomach upset to target therapy.
