A cat that vomits after eating a can but is jumping around may be caused by eating too fast or gastrointestinal irritation. You need to continue to observe whether the cat has other abnormalities. If vomiting, diarrhea, loss of appetite, etc. occur, it is best to go to the hospital for examination. Avoid delays in treatment. If there are no abnormalities, it may be caused by gastrointestinal discomfort or eating too fast. When feeding canned food to cats, it is best to feed it in small amounts and multiple times.
