Illustrated cat food bowl and calorie ring for the guide: Kitten Feeding Chart by Age: Calories and Meals

Kittens need two to three times resting energy. See calories by age, meal counts and when to move to adult food.

Why kittens need more

Kittens grow fast. Under four months they need about 2.5 times resting energy. From four to twelve months, about 2 times. A 4 lb kitten (1.8 kg) has an RER near 109, so it needs about 270 calories at 2.5 times.

Meals by age

Track growth

Weigh weekly. Steady gain is the goal. A kitten that loses weight, stops eating or seems weak needs a vet visit the same day. Orphaned kittens need special feeding guidance.

Moving to adult food

Most cats move to adult food near 12 months. Larger breeds may take longer. Switch slowly over a week. Our kitten feeding calculator uses growth factors for each stage.

Kitten calorie chart by weight

Kitten weightResting energyUnder 4 months (×2.5)4–12 months (×2.0)
2 lb (0.9 kg)~65~162~129
3 lb (1.4 kg)~88~220~176
4 lb (1.8 kg)~109~272~218
6 lb (2.7 kg)~148~370~296
8 lb (3.6 kg)~184~460~368

Pick the column that matches your kitten’s age. A kitten that weighs 6 to 8 pounds is usually past four months, so use the 4–12 month column. All numbers are starting estimates in kcal per day.

Weaning: weeks 4 to 8

Kittens usually start tasting solid food near four weeks and are mostly weaned by eight weeks. Offer a gruel of kitten food mixed with warm water, then thicken it over time.

Orphaned kittens need kitten milk replacer and guidance from a vet. Cow’s milk can upset their stomachs and should not be used.

Wet, dry or both?

Kittens have small mouths and stomachs. Wet food or softened dry food is easy to eat. Dry kitten food can work well once teeth are in.

Choose a food that says it is complete and balanced for growth or for all life stages. Adult food does not have the right nutrient levels for a growing kitten.

Meal plan example

A 4 lb kitten under four months needs about 272 calories. Split that across four meals, and each meal is about 68 calories. With a wet food at 80 calories per can, that is about 0.85 can per meal. If you give half dry and half wet, adjust each portion by its own calories.

At six months, drop to three meals. Many cats move to two meals a day by one year.

Track growth

Weigh your kitten every week at the same time of day. A steady gain is the goal. Many kittens gain roughly 100 grams, or a little under a quarter pound, per week in the early months.

Write the weights down. Share the chart with your vet at checkups. A kitten that loses weight, stops gaining for two weeks, or looks bloated needs a vet visit.

Common mistakes

Frequently asked questions

Can kittens eat adult cat food? A few bites will not hurt, but it should not be the main diet. Growth needs more protein, fat and minerals.Should I free-feed a kitten? Some vets allow it for lean, growing kittens. Weigh weekly. If weight rises too fast, switch to measured meals.When should my kitten move to adult food? Around twelve months for most cats. Large breeds may need longer. Ask your vet.

Conclusion

Feed a growth formula, split the day into small meals and weigh weekly. Use the kitten feeding calculator for a starting number. Then let growth, appetite and your vet guide the changes.

Try it: get an estimate for your cat with the cat calorie calculator. Kittens, pregnant or nursing cats and cats with medical conditions need individual vet advice.
