How Much Should I Feed My Cat? Portion Guide by Age and Weight

One of the most common questions cat owners ask is also one of the simplest to get wrong: how much food should I actually put in the bowl? Too little, and your cat loses weight and energy. Too much, and the extra grams creep on quietly until your vet mentions the word "overweight" at a check-up. The good news is that getting portions right is not complicated — it just takes a little measuring, a little observation, and a willingness to adjust as your cat grows and ages.

Why Portions Matter More Than the Brand

Cats are very good at convincing us they are starving. A loud meow at the kitchen door does not always mean an empty stomach — cats learn quickly that begging works. Most healthy adult cats need somewhere between 200 and 300 calories a day, but that range shifts a lot depending on size, age, activity level, and whether your cat is spayed or neutered. Neutered cats, for example, typically need around 20 percent fewer calories than intact cats of the same size.

Free-feeding — leaving a full bowl down all day — works for a few self-regulating cats, but for most it leads to steady overeating. Measured meals, served at set times, give you control and give your cat routine. Two meals a day suits most adult cats well.

Portion Guide by Age

Kittens (up to 12 months)

Kittens grow fast and burn a lot of energy, so they need more food per kilogram of body weight than adults — roughly twice as many calories. Feed kitten food, which is richer in protein and fat, in three to four small meals a day up to about six months old, then drop to three meals. A typical 8-week-old kitten

may eat around a quarter to a third of a cup of dry kitten food daily, split across meals, but always check the feeding guide on your food's packaging as a starting point, not a rule.

Adult Cats (1 to 7 years)

Most average-sized adult cats (around 4 to 5 kilograms) do well on roughly half a cup of dry food per day, split into two meals — or the wet-food equivalent, usually one 3-ounce tin per 1 to 1.5 kilograms of body weight per day. Active outdoor cats may need a little more; calm indoor cats usually need a little less. If you mix wet and dry food, reduce each so the total stays the same.

Senior Cats (7 years and older)

Older cats often become less active, so their calorie needs drop — but their need for digestible protein stays high, because aging muscles need support. Senior formulas are designed with this balance in mind. Watch your senior cat's weight closely: gradual weight loss in an older cat is worth a vet visit, not just an extra scoop of food.

Portion Guide by Weight

As a rough starting point for an average indoor adult cat eating dry food:

• 3 kg cat: around 40–55 g of dry food per day
• 4 kg cat: around 55–70 g of dry food per day
• 5 kg cat: around 65–80 g of dry food per day
• 6 kg cat: around 75–90 g of dry food per day

These are starting points only. The feeding guide printed on your cat's food bag is calibrated to that specific food's calorie density, so use it first and adjust from there. If your cat is already overweight, do not guess at a weight-loss portion — ask your vet for a target weight and a daily calorie goal, and reduce gradually.

Measure, Don't Guess

The single biggest portion mistake is eyeballing. A "scoop" from a mug can easily be double the intended amount. Use a proper measuring cup or, better still, a small kitchen scale. Weighing food in

grams is the most accurate method, and it takes about ten seconds. If several people in the household feed the cat, agree on one measure and one schedule so your cat is not getting double dinners.

Don't Forget the Treats

Treats count. The common guideline is that treats should make up no more than 10 percent of your cat's daily calories. A handful of treats here and there, plus a dental chew, plus a lick of something from your plate, can quietly add up to a full extra meal. If you use treats for training or play, subtract a little from the main meals to balance it out.

Check the Body, Not Just the Bowl

The best portion guide is your cat's own body. Once a month, do a quick hands-on check: you should be able to feel your cat's ribs with a light touch, without pressing hard, and see a slight waistline when you look down at them from above. If the ribs are hard to find under a layer of fat, portions are too generous. If the ribs and hip bones feel sharp and prominent, your cat may need more food — or a vet check to rule out a health problem. Weigh your cat every month or two if you can; bathroom scales

work fine if you weigh yourself holding the cat and subtract your own weight.

When to Adjust

Change portions gradually — a sudden switch can upset your cat's stomach. Adjust by about 10 percent at a time, then wait two to three weeks and re-check weight and body condition before adjusting again. Seasons matter too: many cats are less active in winter and may need slightly less food, while a new kitten, a pregnancy, or recovery from illness all call for more.

Wet Food, Dry Food, or Both?

Both can be part of a healthy diet. Wet food has higher moisture content, which supports hydration and urinary health, and it tends to be lower in calories per bite. Dry food is convenient, budget-friendly, and easy to measure precisely. A mix of both is a popular middle ground — just remember to count the calories from both, not each one separately.

Getting your cat's portions right is one of the kindest, simplest things you can do for their long-term health. Measure the food, watch the waistline, and let your cat's body — not their meowing — tell you when the amount is right.
