Cat Food & Calorie Calculator

Daily calories and portion size for kittens and adult cats.

How this calculator works

Cats have a smaller energy budget than dogs but a big need for protein. The calculator uses the standard resting energy formula for body weight, applies a factor for life stage and activity, and converts the result into cups of typical dry food (about 300 kcal per cup) so you can portion meals with confidence.

Frequently Asked Questions

Should cats eat wet or dry food?

Both can work. Wet food adds hydration and is often lower in calories per bite, while dry food is convenient. Many owners feed a mix — the calorie total is what matters most.

How many meals a day do cats need?

Adult cats usually do well with two or more measured meals a day. Free-feeding dry food often leads to overeating and weight gain.

My cat is overweight — what now?

Measure meals instead of free-feeding, use the lower end of activity in this calculator, and ask your vet for a safe weight-loss plan. Crash dieting is dangerous for cats.
