Most kittens eat three to four small meals a day, and the amount climbs steadily from a few tablespoons of food at four weeks old to a measured cup-equivalent of calories by the time they’re approaching their first birthday. The exact number depends on weight, the food’s calorie density, and how fast your kitten is growing—so a printed chart is a starting point, not a rulebook. Below you’ll find practical, age-based numbers, a breakdown of wet versus dry feeding, and the warning signs that tell you to adjust portions or call your vet.
Quick Answer
Kittens need roughly two to three times the calories per pound that adult cats do because they’re building bone, muscle, and organs at a remarkable pace. As a rough guide:
- 0–4 weeks: Mother’s milk or kitten milk replacer only (no solid food).
- 4–8 weeks: Begin weaning onto kitten-formula wet or moistened dry food, 4–6 small meals daily.
- 8 weeks–6 months: 3–4 meals a day, free access to growth-formula food.
- 6–12 months: 2–3 meals a day, transitioning toward adult portions.
Always feed a food labeled for “growth” or “all life stages” per AAFCO standards, and match the portion to your kitten’s actual weight rather than guessing.

Feeding Chart by Age
The chart below uses typical growth weights and average calorie needs. Treat the calorie column as the anchor—it’s the most reliable number—because gram and cup amounts shift dramatically between brands.
| Age | Average Weight | Daily Calories (kcal) | Meals/Day | Food Type |
|---|---|---|---|---|
| 0–4 weeks | 0.2–0.9 lb | Milk/KMR only | 8–12 (every 2–4 hrs) | Queen’s milk or kitten milk replacer |
| 4–6 weeks | 0.9–1.3 lb | ~60–100 | 5–6 | KMR + moistened kitten food |
| 6–8 weeks | 1.3–2.0 lb | ~100–180 | 4–5 | Weaning onto kitten wet/dry |
| 2–3 months | 2.0–4.0 lb | ~180–280 | 4 | Kitten growth formula |
| 3–4 months | 4.0–5.5 lb | ~280–360 | 3–4 | Kitten growth formula |
| 4–6 months | 5.5–7.0 lb | ~330–400 | 3 | Kitten growth formula |
| 6–9 months | 7.0–8.5 lb | ~360–430 | 2–3 | Kitten formula |
| 9–12 months | 8.0–10 lb | ~280–360 | 2 | Kitten formula, begin adult transition |
You’ll notice calorie needs peak somewhere around four to six months and then taper as growth slows. Many owners overfeed during the second half of the first year because they don’t adjust downward—a habit that sets the stage for adult obesity.
Calories Matter More Than Cups
A “cup” of food is one of the least useful units in pet care. A dense, high-protein kibble might pack 500 calories per cup, while an air-puffed budget brand could hold 300. Feed the same cup of each and you’d be giving your kitten wildly different energy.
The number that actually matters lives on the bag or can: kcal per cup or kcal per can. Once you know your kitten’s daily calorie target (use the chart, or better, the calculator), divide it by the food’s calorie density to get the real portion.
A quick example: a 4-pound, three-month-old kitten needs around 250 kcal a day. If your kitten food provides 90 kcal per ⅓ cup, that’s roughly one cup spread across the day. Switch to a food with 120 kcal per ⅓ cup, and the same calories fit into about ¾ cup. Same nutrition, different volume.

Wet Food Guidance
Wet food suits kittens well. It’s high in moisture, which supports hydration and kidney health, and most kittens find the texture and aroma irresistible. The downside is that volume adds up quickly, and an open can spoils within a couple of hours at room temperature.
For a typical kitten between two and six months, you’ll usually offer between ½ a 3-oz can and 1½ cans per meal, depending on weight and calorie density. Check the label: most kitten pâtés run 90–120 kcal per 3-oz can. Match the total daily cans to the calorie target rather than feeding until the bowl is licked clean.
Warm wet food slightly to body temperature if your kitten seems uninterested—a few seconds in a warm water bath (not the microwave to avoid hot spots) revives the aroma. For more on whether to lean wet, see Is Wet Food Better for Cats? and our overall How Much Wet Food Should I Feed My Cat? guide.
Dry Food Guidance
Dry kibble is convenient, shelf-stable, and easy to leave out for kittens who like to graze. Because young kittens have small stomachs and big energy demands, free-feeding dry food during the first few months is often reasonable—their fast metabolism usually keeps weight in check.
Soften kibble with warm water for kittens under eight weeks; their teeth and jaws aren’t ready for hard crunching yet. As they mature, gradually reduce the water until they’re eating it dry.
Measure with an actual kitchen scale or a proper measuring cup, not a coffee mug or a scoop you eyeball. Our How Much Dry Food Should I Feed My Cat? article covers precise measuring, and if your kitten turns up their nose at kibble, Why Is My Cat Not Eating Dry Food? explains common causes.
Mixed Feeding Guidance
Plenty of owners combine wet and dry, and kittens generally thrive on the approach. Wet food provides moisture and palatability; dry food offers convenience and dental texture.
The trick is counting calories from both sources toward one daily total—not feeding a full portion of each. A practical split for a growing kitten might be two wet meals and a measured amount of dry left out for grazing, with the combined calories hitting the daily target.

Factors That Change Feeding Amounts
The chart assumes an “average” kitten, but few kittens are average. Adjust your portions when any of these apply:
- Body condition: A kitten with a visible waist and easily felt ribs is on track. A round belly with no waistline means cut back; a sharply visible spine and ribs means feed more.
- Growth rate and breed: Large breeds like Maine Coons grow longer and need calories for an extended period—sometimes well past 12 months.
- Neuter/spay status: Metabolism slows after surgery. Many kittens need a modest calorie reduction within weeks of being fixed.
- Activity level: A playful, athletic kitten burns more than a sleepy lap-sitter.
- Pregnancy or nursing: A young queen who is pregnant or nursing has dramatically higher needs and should be on a vet-guided plan.
- Medical conditions: Digestive issues, parasites, or chronic illness change both calorie needs and the best food choice.
Calorie requirements genuinely vary by all of these factors, so use the chart as a baseline and watch your individual kitten’s body and energy.
Signs You May Be Feeding Too Much
- A rounding belly with no waist visible from above
- Difficulty feeling the ribs under a layer of fat
- Soft or loose stools, or frequent vomiting after meals
- Rapid weight gain that outpaces normal growth curves
- Leftover food sitting in the bowl meal after meal
Overfeeding in kittenhood often turns into adult obesity, which is harder to reverse than to prevent. If your kitten seems perpetually hungry despite adequate portions, Why Is My Cat Always Hungry? explores the reasons.
Signs You May Be Feeding Too Little
- Ribs, spine, and hip bones sharply visible or prominent
- Low energy, weakness, or reluctance to play
- Slow or stalled weight gain
- A dull, rough coat
- Crying around mealtimes and aggressive eating
An underweight kitten is a medical priority. Young animals have little reserve and can decline quickly, so don’t wait to seek help if the body condition looks poor.
When to Ask a Vet
Talk to your veterinarian before making major diet changes, and especially if your kitten is underweight, overweight, showing signs of illness, was recently weaned too early, or is pregnant or nursing. Very young kittens—particularly orphans on milk replacer—benefit from professional guidance on schedules and amounts because mistakes at that stage have outsized consequences.
Your vet can also confirm whether a “growth” formula is right, recommend a target weight curve, and rule out parasites or conditions that mimic feeding problems. No chart or calculator replaces a hands-on exam.
FAQ
How often should I feed a kitten?
Newborns nurse around the clock. From weaning through about six months, aim for three to four meals a day, then ease to two or three as they approach adulthood. See How Often Should You Feed a Cat? for a fuller schedule.
Can I free-feed my kitten?
Free-feeding dry food works for many kittens because their fast metabolism keeps weight balanced—but it doesn’t suit every kitten, and it makes wet food impractical. Free Feeding vs Scheduled Feeding Cats compares both.
When do I switch from kitten food to adult food?
Around 12 months for most cats, and later for large breeds still growing. Make the change gradually over 7–10 days.
Is wet or dry better for kittens?
Both can work. Wet food helps hydration and palatability; dry is convenient and supports grazing. Many owners do best with a mix.
Can kittens eat human food as treats?
Some foods are safe in tiny amounts, others aren’t. Plain cooked chicken and a little egg are generally fine, while tuna should be occasional. Always check items like cheese or salmon before sharing, and keep treats under 10% of daily calories.
My kitten always seems hungry—am I underfeeding?
Not necessarily. Growing kittens have big appetites. Compare body condition and weight gain to the chart, and review Why Is My Cat Always Hungry? before increasing portions.
Should I feed grain-free or high-protein kitten food?
Kittens need protein for growth, but “grain-free” isn’t automatically better. Read Grain-Free Cat Food: Is It Better? and High Protein Cat Food Guide before deciding.
How much weight should a kitten gain?
Healthy kittens gain roughly ½ to 1 ounce per day in the early weeks. Steady, consistent gain matters more than hitting an exact number on any given day.
Conclusion
Feeding a kitten well comes down to matching calories to age, weight, and body condition—then watching the actual animal in front of you rather than the bag’s generic instructions. Start with the chart, lean on calorie counts over cups, and adjust as your kitten grows, gets neutered, and slows down toward adulthood. Run the numbers through the Cat Food Calculator for a personalized target, weigh portions instead of eyeballing them, and loop in your veterinarian for any major change or warning sign. Get the foundation right now, and you’re setting your cat up for a lean, healthy adulthood. When the time comes to plan for the years ahead, our Senior Cat Feeding Guide will be waiting.
