The amount of wet food a cat should eat depends on various factors, including age, weight, activity level, and overall health. As a general guideline, feeding adult cats approximately 2-4 ounces (57-113 grams) of wet food per meal, with 2-3 meals per day, is recommended. This can vary based on the specific brand and formulation of the wet food, as some products may have different calorie densities. It is important to follow the feeding guidelines on the food packaging and consult a veterinarian to determine the appropriate portion size for your cat's needs. Additionally, it is crucial to monitor your cat's weight and body condition to adjust its feeding amount if necessary.
