Kitten Feeding Guide: What, How Often, and How Much to Feed by Age

Feed your kitten a complete food labelled for growth, little and often, adjusting the amount to its age and body condition until it reaches about 12 months. A kitten builds an entire body in under a year, so it needs more calories and protein per kilogram than an adult cat, served in several small meals because its stomach is tiny. Get the food, the frequency, and the portion right and the rest of feeding is mostly common sense.

This guide sits under our wider cat nutrition guide and pairs with our detail piece on how much to feed a cat. Here is how to feed a kitten from weaning to its first birthday.

Choose a complete growth food

Pick a food labelled for growth, meaning kitten or all life stages, not adult maintenance. Cats are obligate carnivores: they need animal-derived nutrients such as taurine, which is not available from a plant-only diet, and a growing kitten needs them in concentrated form. A growth food typically delivers roughly two to three times the calories per kilogram of body weight that an adult cat needs, because a kitten can double or triple its birth weight in its first few weeks. Check the label says complete (so it meets a recognised growth standard) and that it is formulated for growth; a food marked for adult maintenance only is not suitable under about 12 months.

Wet and dry both work as long as they are complete and made for growth. Wet food adds moisture and suits frequent small meals; dry suits puzzle feeders and free-feeding. Many owners feed a mix, and our wet vs dry cat food comparison walks through the trade-offs.

Feed little and often

Feed several small meals a day rather than one or two large ones, because a young kitten’s stomach holds very little. A useful starting pattern is around 4 meals a day from weaning to about 4 months, around 3 meals from 4 to 6 months, then 2 to 3 meals a day from 6 months onward. Spreading the daily ration out keeps energy steady and avoids the gulp-and-vomit that comes with a single big bowl.

When I first brought my kitten Pixie home at nine weeks, I made the classic mistake of putting down her whole day’s wet food at breakfast. She ate it in two minutes, threw most of it back up on the rug, then cried for more an hour later. Splitting the same amount into four saucers across the day fixed it overnight, and it taught me that with kittens the schedule matters as much as the food. There is more on settling a new kitten in our new kitten guide.

How much to feed by age

Follow the age and weight chart on your chosen food and adjust to your kitten’s body condition, rather than fixing on one number. Manufacturers calculate their charts from the food’s specific calorie content, so a portion that is right for one brand may be wrong for another. As a rule of thumb, a kitten needs far more food per kilogram than an adult because so much of it is fuel for growth.

The practical test is your kitten’s shape: you should be able to feel the ribs under a light covering, with a visible waist from above, and no round, pot-bellied look once the meal has settled. Growing kittens are meant to eat a lot and look sturdy, but they should not be fat; starting a cat overweight sets up obesity, which is a leading preventable problem and raises the risk of diabetes and joint disease later. If you are unsure, our guide to cat obesity and weight loss covers body condition scoring, and weigh-ins at your kitten’s vaccination visits give you a steady check.

Weaning: from milk to solid food

Weaning is the gradual move from the mother’s milk to solid food, running roughly from 4 to 8 weeks of age. From about 4 weeks, kittens start lapping a gruel made from kitten food softened with a little warm water or a kitten milk replacer; the mixture is thinned less and less over the following weeks until, by around 8 weeks, they eat solid kitten food and have stopped nursing. Most kittens go to new homes already weaned, so you usually start with solid growth food on day one.

Never offer cow’s milk as a drink: many cats are lactose intolerant, and it commonly causes diarrhoea, as we explain in can cats drink milk. Fresh water should always be available instead, and getting a kitten used to drinking is a good habit; see how to get a cat to drink more water.

Transition to adult food

Switch to adult food when growth slows, which is around 12 months for most cats and later for large breeds. A Maine Coon or similar large breed can keep growing until about 18 to 24 months, so it stays on kitten food longer. Adult maintenance food carries fewer calories and is balanced for a cat that is no longer building bone and muscle, which is exactly why it is not right earlier.

Make any diet change gradually over about 7 days: start with mostly the old food and a little of the new, then shift the balance day by day until you have fully changed over. A sudden swap is the usual cause of the loose stools that follow a new bag of food. The same gentle method applies any time you change your cat’s diet for life, which is one reason it is worth getting the habit right now.

This guide is general information, not a diagnosis or a feeding prescription for your individual kitten. Your own vet can weigh your kitten, score its condition, and confirm the right food and amount for its breed, age, and health, so check anything that worries you with them.
