How Much to Feed a Kitten by Age
How Much to Feed a Kitten by Age
Most kittens need roughly 2 to 3 times more calories per pound than adult cats, split across 3 to 4 meals a day until they hit 6 months. Below is a working chart by age and weight, plus the math to portion dry or wet food without guessing.
The Quick Chart
Use kitten-formula food (labeled "for growth" or "all life stages" per AAFCO). Adult food doesn't have enough protein, fat, DHA, or calcium for a growing kitten.
| Age | Weight (typical) | Daily calories | Meals per day | Food type |
|---|---|---|---|---|
| 0–4 weeks | 0.2–1 lb | 22–28 kcal per 100g body weight | Every 2–4 hrs | Queen's milk or kitten milk replacer (KMR) |
| 4–8 weeks | 1–2 lb | 130–200 kcal | 4–5 | Wet food slurry, transition to solids |
| 8 weeks–4 months | 2–4 lb | 200–350 kcal | 4 | Wet + dry kitten food |
| 4–6 months | 4–6 lb | 300–450 kcal | 3 | Wet + dry kitten food |
| 6–9 months | 6–9 lb | 350–500 kcal | 2–3 | Kitten food, slow taper |
| 9–12 months | 8–10 lb | 250–350 kcal | 2 | Transition to adult food at 12 months |
Numbers assume a healthy body condition score of 4–5 out of 9. Very active or lean kittens need more. Persian, Ragdoll, and Maine Coon kittens grow for 15–18 months and stay on kitten food longer.
Worked Example: A 12-Week-Old at 3 lb
A 3 lb kitten at 12 weeks needs about 250 kcal per day. If your dry food is 400 kcal per cup (check the bag, this varies wildly), that's 5/8 cup, or about 55 grams. Split into 4 meals, that's roughly 14g per meal, or 3 tablespoons of dry kibble each feeding.
If you're mixing 50/50 with wet food at 100 kcal per 3 oz can: give 1.25 cans of wet plus 30g of dry, split across the day.
Weigh food on a $12 kitchen scale. Measuring cups are off by up to 30% with kibble.
Milestones by Age
0 to 4 Weeks: Milk Only
Neonatal kittens need queen's milk or KMR every 2 to 4 hours, including overnight. Cow's milk causes diarrhea and dehydration. Kittens this young can't regulate body temperature or urinate on their own, so bottle-feeding is a full-time job. If you're fostering orphans, call your vet within 24 hours for a weight-tracking plan. A healthy kitten gains 10–15g per day.
4 to 8 Weeks: Weaning
Start mixing wet kitten food with warm water into a slurry. Offer it in a shallow dish 4 to 5 times a day. Keep KMR available. By week 7, most kittens eat solid wet food and drink water from a bowl. Introduce dry kibble softened with warm water at week 6.
8 Weeks to 4 Months: The Growth Sprint
This is when kittens double or triple in weight. Free-feeding dry food works for most kittens this age because they burn calories fast and self-regulate well. Wet food twice a day on top of dry gives them the moisture and protein their developing muscles need. Don't skip the wet food. Cats fed only dry food long-term have higher rates of urinary crystals.
4 to 6 Months: Slow Down the Portions Slightly
Growth rate slows. Move to 3 measured meals instead of free-feeding. This is also when kittens should be spayed or neutered, which drops metabolic rate by 20 to 30% within weeks. Cut portions by roughly 15% after surgery or you'll see a paunch by 8 months.
6 to 12 Months: The Taper
Drop to 2 meals a day. Kittens are still growing but the calorie-per-pound need is falling. Weigh monthly. If you can't feel ribs under a thin fat layer, cut portions by 10%.
When to Switch to Adult Food
At 12 months for most breeds, or 15 to 18 months for large breeds (Maine Coon, Ragdoll, Norwegian Forest). Transition over 7 to 10 days by mixing increasing amounts of adult food. Sudden switches cause GI upset in about 1 in 4 cats.
Wet, Dry, or Both?
Both. Wet food is 70 to 80% water and helps prevent urinary issues. Dry food is calorie-dense and cheaper per meal. A common split: two wet meals plus a small bowl of dry kibble measured out for the day. Fresh raw diets (like Raw Wild) can work but need to be AAFCO-balanced for growth. A homemade raw diet without a veterinary nutritionist's recipe will cause deficiencies.
Automated feeders like Chef Paw are useful for portion control once your kitten is past 4 months and eating on a schedule.
Red Flags
Call your vet if your kitten:
- Loses weight or fails to gain for more than 2 days
- Refuses food for over 24 hours (kittens can develop hepatic lipidosis fast)
- Has diarrhea for more than 24 hours
- Has a bloated belly plus lethargy
- Vomits more than twice in a day
Cost Reality Check
Feeding a kitten kitten-formula food runs roughly $30 to $70 per month depending on brand and dry-vs-wet ratio. Premium wet-only diets can hit $120 per month for a 6-month-old. Budget for it before you bring the kitten home.
