Cats may experience diarrhea or vomiting after eating canned food straight from the refrigerator because their digestive systems are sensitive and cannot tolerate excessively cold food.

If your cat experiences diarrhea, vomiting, or other symptoms after eating cold canned food, it is recommended to consult a veterinarian promptly for professional diagnosis and treatment advice. To avoid this, owners should choose canned food that is appropriate for their cat's appetite and taste, and try to ensure the cat finishes the food in one sitting, avoiding prolonged refrigeration.
