An obstruction in the intestinal system, which may be fatal, can result from a cat eating metal, like a coin. The metallic object may become stuck in the gut, colon, or esophagus and cause a blockage based on its shape and dimensions.  Nausea, a decrease in hunger, pain in the abdomen, and constipation are just a few of the symptoms that can result from a blockage. In extreme circumstances, it may result in organ damage, electrolyte disturbances, and exhaustion. In addition, some metals, like zinc, can be hazardous to cats if consumed in significant amounts. Zinc poisoning can cause anemia, liver or renal dysfunction, anorexia, nausea, diarrhea, and drowsiness.
