When it comes to the amount of food to give a cat, there are no hard and fast rules. One cat's daily food needs is not the same as another's. You have take into consideration your pet's age, activity level, health, body type, size, and even breed. If you're using formulated or canned cat food, check the label. There's a guideline there, but you need not follow it to the letter. If your cat is big, he may need more than the recommended portion. Similarly, if your cat is the kind who races around the house all day, he may need more than a cat who sleeps 16 hours a day.

Your cat veterinarian can also advise you about your cat's ideal weight. Many cats are overfed and under-exercised, resulting in fat and lazy pets. When in doubt, start by giving a little less than recommended in the label. Do this for about a month, then weigh your pet. If he is underweight, slightly increase the amount of food you give him. If he is heavier than the ideal weight, reduce the portion.

Cats are not big eaters, but to keep them healthy, you should give them at least two meals a day. Kittens, however, need more as they are full of energy. Kittens up to 5 months of age need 4 to 5 meals a day to meet their daily caloric needs. At age 5 to 12 months, you can gradually reduce the number of meals per day. At 12 months, switch your kitten to adult cat food.
