How many grams of cat food should a cat eat per day?
A cat eats about 38 grams of cat food a day.
Generally, kittens need to be fed four to five times a day, while adult cats need to be fed once or twice a day. When a two-month-old kitten weighs 0.8 to 1.2 kg, it needs about 38 grams of cat food per day. When a kitten reaches three months old, it eats an average of about 50 grams of cat food per day, and when a kitten is four months old, it eats about 80 grams of cat food per day. 
When a kitten is six months old, it should eat about 90 grams of food per day. When it is seven months old, it should eat about 70 grams per day. When it is an adult, it should be fed about 100 to 120 grams of cat food per day. When an adult cat weighs less than 3 kilograms, it should eat 30 to 50 grams of cat food per day. When an adult cat weighs more than 3 kilograms, it should eat 70 to 100 grams of cat food per day.
Precisely calculating a cat's food intake is difficult, and it's not necessary to strictly adhere to standard portion sizes. This is because the nutritional composition of different cat foods varies, each cat's daily activity level differs, and cats at different growth stages have different dietary needs. Adult cats should eat adult cat food, and the feeding amounts can be referenced from the feeding guidelines on the cat food packaging.
