How much Cat food for a 3 year old cat?

How much food a cat needs depends on the individual's shape, size, appetite and activity level. A small cat will need less food compared to a large cat. In addition to this, the quality of food greatly contributes to how much food a cat needs. Low quality food usually includes cheap ingredients (using plant sources instead of meat sources for example) doesn't provide a cat with adequate nutrients, so the cat has to eat more of it. A high quality food made with lots of meat will fill a cat up using a smaller amount per meal.

Typically, an average cat needs around 200g of wet food per day, and much less if you feed dry food as dry food usually contains more calories. If your cat is 11 to 15 lbs. the average is 1 to 1 1/2 cups of dry cat food a day. Or you could give your cat a 6 1/2 oz. can.
