Kittens grow at an astonishing pace, and feeding them right fuels healthy development without setting up weight problems later. Here's how often and how much to feed at every stage, from nursing to their first birthday.
Feeding a kitten is a moving target. In their first year, kittens transform from helpless newborns into nearly full-grown cats, and their nutritional needs shift dramatically along the way. Feed them too little and you stunt that crucial growth; feed them too much, or the wrong food, and you set the stage for obesity and health problems down the road. This guide walks through the kitten feeding schedule by age, how much to offer, and how everything changes as your kitten matures.
Why kittens eat differently from adult cats
Growing kittens need roughly two to three times the calories per pound that an adult cat does, because they're building bones, muscles, and organs at a furious rate. They also have tiny stomachs that can't hold much at once, which is why young kittens eat small meals frequently throughout the day. On top of that, kittens require a food specifically formulated for growth, with higher protein, fat, and key nutrients than adult maintenance food provides. Meeting these needs is the whole point of a proper kitten feeding routine.
The feeding schedule by age
- 0–4 weeks: Nursing from mom, or bottle-feeding kitten milk replacer every 2–4 hours around the clock if orphaned. Never give cow's milk.
- 4–6 weeks: Weaning begins. Offer wet kitten food or moistened kibble alongside nursing, 4–6 small meals a day.
- 6–8 weeks: Fully weaned onto kitten food, 4 meals a day.
- 2–6 months: The fastest growth phase — feed 3–4 meals a day of a complete kitten food.
- 6–12 months: Growth slows; you can move to 2–3 meals a day.
- 12 months and up: Transition to adult cat food, typically 2 meals a day.
Frequent feeding suits a kitten's small stomach and high energy needs. The schedule divides the daily amount across more meals — it doesn't increase the total beyond what your kitten needs.
How much to feed
The right amount depends on your kitten's age, current weight, and the specific food, since calorie density varies. Start with the feeding guide on your kitten food's packaging, which gives amounts by weight and age, then adjust based on body condition and growth. Because kittens grow so fast, you'll need to increase portions regularly as they gain weight. Our cat calorie calculator accounts for life stage, the kitten weight tracker helps you monitor healthy growth, and for the wider context see our guide on how much to feed a cat.
Choosing the right kitten food
Feed a food specifically formulated for kittens (or labeled “all life stages”) and complete and balanced to AAFCO standards for growth. Kitten formulas pack the extra calories, protein, and nutrients — like the amino acid taurine — that a developing cat needs. As obligate carnivores, kittens thrive on meat-based, high-protein diets, so look for a named animal protein as the first ingredient. Avoid feeding adult cat food or, worse, dog food to a kitten, since neither meets a growing kitten's needs.
Wet, dry, or both?
Kittens can eat wet food, dry kibble, or a combination, as long as it's a complete kitten formula. Many vets favor including wet food, which is high in moisture and helps establish good hydration habits early — important for a species prone to urinary issues. Dry food is convenient and can be left out a little longer, though portion control matters. A mix of both is a popular, balanced approach; offering both textures young also makes your cat more adaptable as an adult.
Scheduled meals vs. free-feeding
For young kittens in their rapid-growth phase, having food readily available across several small meals supports their needs. As your kitten approaches and passes six months, though, shifting toward measured, scheduled meals helps prevent the overeating and weight gain that free-feeding encourages. Measuring portions also lets you monitor appetite, which is one of the first things to change when a cat is unwell. Scheduled feeding tends to set up healthier lifelong habits than leaving a bowl perpetually full.
Hydration matters
Cats evolved from desert animals and have a naturally low thirst drive, which makes good hydration habits worth building from kittenhood. Always provide fresh, clean water, consider including wet food for its moisture, and note that some cats prefer running water from a fountain. Our cat water intake calculator helps you gauge whether your kitten is getting enough. Good hydration early supports kidney and urinary health for life.
Treats and the 10% rule
Treats are useful for bonding and training, but keep them to no more than about 10% of daily calories so they don't unbalance a growing kitten's carefully formulated diet. Use small, kitten-appropriate treats, and be cautious with human food — many items are unsafe. See our guides on human foods cats can eat and the all-important foods toxic to cats before sharing anything from your plate.
When to switch to adult cat food
Most kittens are ready to transition to adult cat food at around 12 months of age, when growth is essentially complete. Large breeds like the Maine Coon, which keep growing for longer, may stay on kitten food until 18 months or more — your vet can advise. Switching too early deprives a still-growing kitten of needed nutrients, while staying on calorie-dense kitten food too long risks weight gain. Whenever you switch, transition gradually over 7 to 10 days to protect digestion.
Keeping your kitten lean
It's tempting to indulge a hungry kitten, but the goal is steady growth, not a roly-poly kitten. Overfeeding sets up obesity, which is one of the most common and harmful health problems in adult cats. You should be able to feel your kitten's ribs easily under a light covering and see a waist from above. Monitoring body condition as they grow, and adjusting portions accordingly, is the single best thing you can do for their long-term health — our guide on how long cats live covers how a healthy weight extends lifespan.
Feeding orphaned or very young kittens
If you find yourself caring for an orphaned kitten without a mother, the rules change. Kittens under four weeks can't eat solid food and need a proper kitten milk replacer (KMR), fed warm from a kitten bottle every few hours around the clock — never cow's milk, and never on their back, which risks aspiration. Very young kittens also need help staying warm and stimulating to toilet. Hand-rearing is demanding and easy to get wrong, so if you're caring for orphaned kittens, get your vet's guidance early; they can show you safe technique and a feeding schedule suited to the kitten's age and weight.
Signs your feeding is on track
Your kitten's body tells you whether you've got it right. A well-fed kitten gains weight steadily, is playful and energetic, has firm, well-formed stools, and sports a soft, glossy coat. Weigh your kitten regularly during these months — consistent weekly gain is one of the best signs of health. Pot-bellied roundness with poor growth can signal parasites and warrants a vet check, while a kitten who isn't gaining, refuses food, or has persistent diarrhea needs prompt attention. Steady growth, good energy, and healthy stools are the trio to watch for.
The bottom line
Feed kittens a complete kitten food frequently — 4 meals a day in the early months, easing to 2–3 as they grow — adjusting the amount as they gain weight and keeping them lean. Choose a high-protein, growth-formulated food, include wet food for hydration, count treats in the daily total, and switch to adult food around 12 months. Steady, measured feeding on a sensible schedule lays the foundation for a healthy adult cat.
Frequently asked questions
How often should I feed my kitten?
Feed 4 small meals a day from weaning to about 6 months, then 3 meals from 6 months, easing to 2–3 meals as they approach a year. Young kittens have tiny stomachs and high energy needs, so frequent feeding suits them. The schedule divides the daily amount across more meals rather than increasing the total.
How much should I feed my kitten?
Start with the feeding guide on your kitten food's packaging, which gives amounts by weight and age, then adjust to keep your kitten lean and growing steadily. Because kittens grow fast, increase the portion regularly as they gain weight. You should be able to feel the ribs easily and see a waist.
When should I switch my kitten to adult cat food?
Most kittens transition to adult food around 12 months, when growth is complete. Large breeds like Maine Coons may stay on kitten food until 18 months or more. Switching too early shortchanges growth, and too late risks weight gain. Transition gradually over 7 to 10 days.
Can kittens drink milk?
No — most kittens can't digest cow's milk, and it commonly causes diarrhea. Nursing kittens need their mother's milk or a proper kitten milk replacer (KMR), never cow's milk. Once weaned, fresh water is all a kitten needs to drink.
