Important disclaimer
This calculator provides general portion guidance only. The right amount for your cat can vary based on body condition, breed, medical needs, appetite, and food brand. Always check packaging guidance and speak to your vet if your cat is underweight, overweight, or has a health condition.
How much should I feed my cat per meal?
The right portion depends on your cat’s weight, age, activity level, food type, and how many meals they eat each day. Some owners overfeed without realising it, especially with dry food, because small amounts can look too little even when they contain plenty of calories.
A practical way to feed your cat is to calculate the total daily amount first, then divide that into equal meal portions. That gives you a clear, repeatable routine and makes it easier to spot appetite changes.
How to calculate your cat’s food portions
Start with your cat’s weight and estimate their daily calorie needs. Then convert those calories into grams of wet food, dry food, or a mixed-feeding amount based on the food type.
Once you know the daily total, divide it by the number of meals per day. For example, if your cat needs 240 grams of wet food daily and eats three meals, that works out to 80 grams per meal.
Cat food portion guide by weight
| Cat weight | Typical daily wet food | Typical daily dry food |
|---|---|---|
| 2 to 3 kg | 160 to 210 g | 35 to 45 g |
| 3 to 4 kg | 210 to 260 g | 45 to 55 g |
| 4 to 5 kg | 240 to 320 g | 55 to 70 g |
| 5 to 6 kg | 250 to 360 g | 65 to 80 g |
These are general guides only. Always adjust for activity, life stage, body condition, and food brand.
Wet vs dry food portion differences
Wet food contains much more moisture, so your cat usually needs a larger weight of wet food to get the same calories. Dry food is far more concentrated, which means even small portions can contain a lot of energy.
That is why dry food is easy to overfeed. It is also why portion calculators are useful: they help turn calorie needs into realistic meal amounts you can actually measure.
How often should you feed your cat?
Most adult cats do well with two meals a day. Kittens usually need more frequent feeding, often three to four meals daily. Senior cats can often stay on two meals a day, though some prefer smaller, more frequent meals.
Cats are creatures of habit, so regular meal timing usually works better than inconsistent feeding. If your cat begs a lot, eats too quickly, or struggles with portion control, dividing the daily total into more meals can help.

Frequently Asked Questions
How much should I feed my cat per meal?
It depends on your cat’s weight, age, activity level, food type, and how many meals they eat each day. A per-meal calculator helps split the daily amount into practical portions.
How many times a day should I feed my cat?
Most adult cats do well on two meals per day. Kittens often need three to four meals, while some seniors do better with smaller, more frequent meals.
Is wet food different from dry food for portion sizes?
Yes. Dry food is much more calorie-dense, so cats usually need a much smaller weight of dry food than wet food to get the same calories.
Should I split food evenly between meals?
Usually yes. Splitting food evenly is a simple and effective starting point, though some cats do better with a slightly larger morning or evening meal.
How do I know if I am overfeeding my cat?
Common signs include steady weight gain, reduced waist definition, difficulty feeling the ribs, and persistent overconsumption when food is available.
Should neutered cats eat less?
Often yes. After neutering, many cats have lower energy needs, so their daily food amount may need to be reduced to avoid unwanted weight gain.
