Kitten Feeding Amounts: 8 Weeks to 12 Months
How much should a kitten eat? Daily amounts by age from 8 weeks to a year — wet and dry portions, growth kcal targets and when to move to adult rations.
How Much Should You Feed a Kitten?
A kitten needs 2.5 to 3 times its resting energy requirement during growth — per pound, roughly two to three times an adult cat's intake. An 8-week-old, 2 lb kitten needs about 160-200 kcal per day, and a 5-month-old, 5.5 lb kitten needs about 330-350 kcal, which already exceeds the 260 kcal a 10 lb adult eats per the how much to feed a cat guide.
The base formula is the same one used for every cat: RER = 70 x (weight in kg)^0.75. The growth multiplier does the work — about 3.0 until 4 months, 2.5 to 6 months, then tapering to 1.4-1.6 by 12 months. The calories growing kittens need are recalculated as both the weight and the multiplier change.
Because kitten stomachs are tiny while energy needs are huge, split the daily amount into 3-4 meals per day, and more than that under 12 weeks.
Kitten Portions by Age: 8 Weeks to 12 Months
The age bands below give typical weights, daily calorie targets and meal counts across the first year. The portion chart for kittens converts each band into cans and cups per day for specific food densities.
Read the table by age first, then confirm against weight: a 3-month kitten near 3 lb belongs in the 250-320 kcal band, while an unusually large 3-month kitten already at 4.5 lb feeds toward the top of it. The calorie target follows the body doing the growing, not the birthday alone.
The highest-traffic mistake happens at 6 to 7 months: kittens look adult-sized but are still growing, so do not switch to adult amounts yet. A 7-month, 7 lb kitten still needs about 380 kcal — well above the 260 kcal an adult of similar weight eats. Feed a food carrying an AAFCO growth or all-life-stages statement until 12 months; kitten food is more energy-dense and protein-dense than adult food, and an obligate carnivore in peak growth needs both.
| Age | Typical weight | Daily kcal | Meals per day |
|---|---|---|---|
| 8-12 weeks | 2-3 lb | 160-250 | 4 |
| 3-4 months | 3-4.5 lb | 250-320 | 3-4 |
| 5-6 months | 5-6.5 lb | 330-380 | 3 |
| 7-9 months | 6.5-8 lb | 350-400 | 2-3 |
| 10-12 months | 8+ lb | taper to 260-300 | 2 |
Under 8 Weeks: Newborn and 4-Week-Old Kittens
Kittens under 4 weeks old are fed kitten milk replacer (KMR) — never cow's milk, which kittens cannot digest after early infancy and which causes dehydrating diarrhea. The working dose is about 8 ml of prepared formula per ounce of body weight per day, split across feeds every 2 to 4 hours around the clock, overnight included for the youngest.
At 4 to 5 weeks, introduce gruel: wet kitten food blended with KMR into a slurry the kitten laps rather than nurses. From 6 to 8 weeks, thicken the gruel progressively and wean fully onto wet kitten food, keeping the meal count at four or more small servings.
Bottle-feeding technique, feed timing by week and stimulation routines belong to the kitten feeding schedule, which covers the under-8-weeks period hour by hour. This page stays brief on newborns deliberately; a rescue scenario deserves the dedicated walkthrough.
Wet, Dry or Both for Growing Kittens
Wet kitten food, at roughly 100-110 kcal per 3-oz can, fits obligate-carnivore growth precisely: high animal protein, easy for small jaws to chew, and 70-80 percent moisture that builds early hydration habits in a species with a weak thirst drive. The full wet food for kittens guide covers can counts by age.
Dry kitten food runs about 450-500 kcal per cup and is acceptable to free-feed only for kittens under roughly 5-6 months, because growth burns everything an unweaned appetite takes in. That allowance expires at neutering age: switch to measured meals when the surgery happens.
Spay or neuter surgery reduces a kitten's energy needs by 25 to 30 percent almost overnight, typically at 5-6 months. This is the classic moment kittens start getting fat — the growth multiplier is already falling, the metabolic drop lands on top, and the free-fed bowl keeps flowing. Cut portions at the surgery, not months later when the fat is visible.
Is Your Kitten Eating Enough? Growth Tracking
Healthy kittens gain about one pound per month for their first six months, which yields the useful check: weight in pounds should roughly equal age in months. A 4-month kitten near 4 lb is on curve; a 4-month kitten at 2.5 lb is not, and its portions need review alongside a health check.
Weigh weekly on a kitchen or baby scale. Steady gain with ribs still palpable under a thin cover means the amounts are right; visible ribs and spine mean feed more, and a rounding belly on a post-neuter kitten means the 25-30 percent cut is overdue. A plateau or a loss in a growing kitten is an urgent veterinary issue, not a portion-tuning problem — kittens have no reserves and decline fast.
From 10 to 12 months, taper toward adult portions and transition to the adult math in the how much to feed a cat guide: 1.2 x RER for the neutered young adult your kitten is becoming. Rather than re-deriving the shifting growth multipliers every month, get exact portion sizes from the calculator — it applies the right factor for your kitten's current age and weight, and you get your cat's target updated as fast as the kitten grows.
Frequently asked questions
- How much should I feed my 6 month old kitten?
- About 330-380 kcal per day across 3 meals for a typical 5.5-6.5 lb kitten — still 2-2.5 x RER. Do not drop to adult portions yet; growth continues to 12 months.
- How much should an 8 week old kitten eat?
- Roughly 160-200 kcal per day of wet kitten food split into 4 small meals — about 1.5-2 three-oz kitten cans.
- When do I switch from kitten to adult food amounts?
- Taper between 10 and 12 months. After spay or neuter, cut portions 25-30 percent to match the metabolic drop, whenever the surgery happens.
- Can I free-feed my kitten?
- Free-feeding dry kitten food is acceptable under about 5-6 months of age. After neutering, switch to measured meals to prevent early weight gain.
