The amount of food you should feed your cat depends on its weight, age, and activity level.
Most cats will eat about 1/4 to 1/2 cup of food per day.
Cats who are less active might need less food, while those who are more active might need more.
Some cats may be overweight or underweight and require a different amount of food as well.
The amount of food a cat needs is dependent on the age, weight and activity level of the cat.

The recommended feeding guidelines for cats are as follows:
8-10 weeks old – 3/4 cup
11-14 weeks old – 1 cup
15+ weeks old – 1.5 cups
Some cats are more active than others, so it’s important to take that into account when deciding how much to feed your cat. If your cat is indoors and mainly sleeps all day, you might want to feed them a little less than if they were an outdoor cat that spends most of the day running around.
This article will tell you how much food you should be feeding your cat based on their activity level.
You should not just feed your cat based on their weight because they can have different weights but still need the same amount of food. You should also not just feed them based on how hungry they look because they can be starving but still not want to eat anything.
