Kittens 2–6 months: feeding a fast-growing kitten

This is peak growth. Your kitten may triple in weight, swap baby teeth for adult ones and burn through energy at an amazing rate. Here’s how much to feed, how often, and what else to plan for.

What's happening

What happens from 2 to 6 months

Rapid growth. Many kittens put on around 1 lb (450 g) a month. Re-check portions every 2–3 weeks.
Teething. Adult teeth push out the baby teeth from around 3–4 months. Chewing on everything is normal; give safe chew toys.
Vaccinations. Core kitten vaccines usually start at 6–8 weeks and are repeated every 3–4 weeks until about 16 weeks. Your vet will set the exact schedule.
Spay or neuter. Many vets now recommend this by around 5 months, before a kitten can get pregnant or start spraying.
Socialization. New people, sounds, handling and carrier practice now make for a calmer adult cat.

Feeding

How much and how often

Kittens need far more calories per pound than adult cats. The Merck Veterinary Manual puts growing kittens at about 2.5 × resting energy, and the factor starts to fall from around 4 months as growth slows, so we use about 2.0 from 4 months. In practice:

A 3 lb (1.4 kg) kitten under 4 months needs roughly 220 kcal a day.
A 5 lb (2.3 kg) kitten at 5 months needs roughly 260 kcal a day.

Our Kitten Plan builder converts that into cans and cups for your kitten’s exact weight.

Meals: 4 a day until about 3 months, then 3 a day until 6 months. Some owners leave measured dry food out for grazing between wet meals.
Food: stick to food labeled complete and balanced for growth or all life stages. Adult food doesn’t have enough calories, protein or minerals for this stage.
Variety: offer a couple of textures and proteins now. Kittens exposed to variety are usually less picky later.
Treats: keep them to 10% of daily calories.
Check body condition: you should feel the ribs easily without seeing them, with a visible waist from above.

Your checklist

What you need this stage

A sturdy carrier for vet visits, left out at home so it becomes familiar
Tall, stable scratching posts, both vertical and horizontal
Interactive toys: wand toys, balls and puzzle feeders
Kitten nail clippers and a soft brush, introduced gently
A microchip and a breakaway collar with ID
Kitten-safe chew toys for teething

See our kitten essentials checklist for what we’d actually buy.

Call your vet if…

Vomiting more than once, or diarrhea lasting more than 24 hours
Not eating for a day, or sudden lethargy
Sneezing, eye discharge or coughing
A swollen, pot-bellied tummy, or worms in the stool
Weight loss, or no weight gain over two weeks

Portions change every few weeks

Re-run your kitten’s plan whenever they’ve gained weight. It takes 30 seconds.
