Stomach
As the food exits the esophagus, it enters the stomach where the digestive process begins. The stomach chemically and mechanically breaks the food into smaller pieces before the food enters the small intestine. Vomiting is the major sign that indicates stomach irritation. Overeating and dietary intolerance can result in stomach irritation. Cats have curious nature and they may ingest an object that is not meant for eating and may become lodged in the stomach. Vomiting can be an indication of other diseases such as hormonal imbalance, kidney disease, or lie disease. Lab work and abdominal x-rays can help in determining the underlying cause of the irritated stomach to begin treatment therapy.
