Feeding a growing kitten is fundamentally different from feeding an adult cat. Kittens require significantly more calories per pound of body weight, higher protein levels, and carefully timed meal frequencies to support rapid growth, bone development, and immune system maturation. This comprehensive guide provides feeding charts organized by age (2, 4, 6, 8, and 12 months) and explains AAFCO nutritional standards that every kitten food must meet.
AAFCO Nutritional Standards for Growing Kittens
The Association of American Feed Control Officials (AAFCO) sets strict minimum nutrient levels for kitten foods labeled "for growth" or "for all life stages." These standards are higher than adult maintenance levels because kittens are building muscle, bone, organs, and tissue at an extraordinary rate.
AAFCO 2026 Kitten Nutrient Requirements (dry matter basis):
| Nutrient | Kitten (Growth) Min | Adult Maintenance Min | Importance |
|---|---|---|---|
| Crude Protein | 30% | 26% | Muscle and tissue development |
| Crude Fat | 9% | 9% | Energy density and brain development |
| Taurine | 0.1% (1000 mg/kg) | 0.1% (1000 mg/kg) | Heart health and vision |
| Calcium | 1.0% (min) / 1.8% (max) | 0.6% (min) / 1.5% (max) | Bone and teeth formation |
| Phosphorus | 0.8% (min) / 1.6% (max) | 0.5% (min) / 1.2% (max) | Bone mineralization |
| Docosahexaenoic Acid (DHA) | 0.05% | Not required | Brain and retinal development |
| Vitamin A | 9,000 IU/kg | 5,000 IU/kg | Vision and immune function |
| Vitamin D | 500 IU/kg | 500 IU/kg | Calcium absorption and bone health |
Kitten Feeding Chart by Age and Weight
The following charts provide daily calorie requirements and food portions based on the WSAVA formula: Daily Calories = 70 × (weight in kg)^0.75 × MER factor. For kittens, the MER factor decreases as they age: 2.5× for 0-4 months, 2.0× for 4-8 months, and 1.6× for 8-12 months.
2-Month-Old Kitten (8 weeks) Feeding Chart
At 2 months, kittens are typically fully weaned and eating solid food exclusively. They need 4 meals per day to maintain stable blood sugar levels.
| Weight (lbs) | Weight (kg) | Daily Calories | Dry Food (cups/day) | Wet Food (cans/day) |
|---|---|---|---|---|
| 1.5 lbs | 0.68 kg | 125 kcal | 0.36 cups | 1.25 cans |
| 2.0 lbs | 0.91 kg | 155 kcal | 0.44 cups | 1.55 cans |
| 2.5 lbs | 1.13 kg | 185 kcal | 0.53 cups | 1.85 cans |
4-Month-Old Kitten Feeding Chart
At 4 months, kittens are in their peak growth phase. Continue with 4 meals per day, though some kittens can transition to 3 meals.
| Weight (lbs) | Weight (kg) | Daily Calories | Dry Food (cups/day) | Wet Food (cans/day) |
|---|---|---|---|---|
| 3.0 lbs | 1.36 kg | 245 kcal | 0.70 cups | 2.45 cans |

Weaning Transition Guide (4-8 weeks)
Weaning is the process of transitioning kittens from mother's milk (or formula) to solid food. This typically begins at 4 weeks and completes by 8 weeks.
- Week 4: Offer a shallow dish of kitten formula mixed with high-quality wet kitten food, warmed to room temperature. The mixture should have a gruel-like consistency. Kittens will initially walk in it and lick it off their paws — this is normal.
- Week 5: Gradually reduce the amount of formula, making the mixture thicker. Offer small portions 4-6 times per day.
- Week 6: Transition to wet kitten food only (no formula). Kittens should be eating voluntarily at this stage.
- Week 7-8: Introduce dry kitten kibble (moisten with warm water if needed). By week 8, kittens should be fully weaned and eating solid food exclusively.
Meal Frequency by Age
Kittens have small stomachs and high metabolic rates, making frequent meals essential for maintaining stable blood glucose levels.
| Age | Meals Per Day | Reason |
|---|---|---|
| 4-8 weeks (weaning) | 4-6 meals | Very small stomach capacity |
| 2-4 months | 4 meals | Rapid growth, high calorie needs |
| 4-6 months | 3 meals | Moderate growth rate |
| 6-12 months | 2-3 meals | Approaching adult metabolism |
| 12+ months (adult) | 2 meals | Adult maintenance |
Growth Weight Chart by Age
The following table shows the expected weight range for kittens from birth to 12 months. Individual variation is normal, but significant deviations may indicate health or nutrition issues.
| Age | Average Weight (lbs) | Weekly Weight Gain |
|---|---|---|
| Birth | 0.2-0.3 lbs | N/A |
| 1 week | 0.3-0.4 lbs | +0.1 lbs/week |
| 2 weeks | 0.5-0.6 lbs | +0.2 lbs/week |
| 4 weeks | 0.8-1.0 lbs | +0.25 lbs/week |
| 8 weeks (2 months) | 1.5-2.5 lbs | +0.5 lbs/week |
| 12 weeks (3 months) | 2.5-4.0 lbs | +1.0 lbs/month |
| 6 months | 5.0-7.0 lbs | +1.0 lbs/month |
| 9 months | 7.0-9.0 lbs | +0.5 lbs/month |
| 12 months | 8.0-10.0 lbs | Adult weight reached |
Kitten Feeding Mistakes to Avoid
- Free-feeding dry food: While convenient, free-feeding makes it difficult to monitor intake and can lead to obesity once kittens reach 6+ months.
- Feeding dog food: Dog food lacks sufficient taurine and has different calcium/phosphorus ratios — it can be fatal to kittens if fed exclusively.
- Giving cow's milk: Most kittens are lactose intolerant after weaning. Cow's milk causes diarrhea and dehydration.
- Overfeeding: Rapid weight gain (more than 2% per week after 3 months) can cause joint problems and obesity in adulthood.
- Underfeeding: Inadequate calories result in stunted growth, poor coat quality, and weakened immune function.
- Feeding adult treats: Treats should not exceed 10% of daily calories, and kitten-specific treats are preferable.
When to Switch from Kitten to Adult Food
Most cats should transition to adult food at 12 months. However, large breeds (Maine Coon, Norwegian Forest Cat, Ragdoll) continue growing until 18-24 months and should remain on kitten food longer. The transition should be gradual over 7-10 days to avoid digestive upset:
- Days 1-2: 75% kitten food + 25% adult food
- Days 3-4: 50% kitten food + 50% adult food
- Days 5-6: 25% kitten food + 75% adult food
- Days 7+: 100% adult food
Conclusion
Feeding a kitten correctly during the first 12 months of life sets the foundation for a lifetime of health. Use the AAFCO "for growth" or "for all life stages" standards as your baseline, follow the age-based feeding charts in this guide, and monitor your kitten's weight weekly. If your kitten consistently falls below or above the expected weight range, consult your veterinarian to rule out parasites, illness, or nutritional imbalances. With proper nutrition, your kitten will grow into a strong, healthy adult cat.
Week-by-Week Kitten Feeding Milestones
From birth to 4 weeks, kittens need milk replacer every 2-3 hours and cannot digest solid food; weight should climb steadily, roughly doubling by week two. At 4-5 weeks, introduce a 'gruel' of warmed replacer mixed with soaked kitten kibble -- this starts weaning. By 6-8 weeks they should eat mostly solid growth food, four small meals a day. From 8 weeks to 6 months, feed 3-4 meals and track weight weekly; a healthy kitten gains about 0.5-1 oz per day early on, then settles. After 6 months, two to three meals suffice as the growth factor eases. Giant breeds (Maine Coon, Ragdoll) stay on growth formula and a higher-calorie target until 18-24 months, not the 12-month birthday used for small breeds.
Use a kitten feeding chart on the fridge: weigh every Saturday, write the number, and mark the day's measured portions. A kitten that misses two meals or stops gaining is a red flag, not a quirk -- call your vet.
Transitioning From Milk to Solid Food (Weaning)
Weaning is a gradual hand-off. Start with gruel so loose the kitten can lap it, then thicken it over 7-10 days as they learn to chew. Never rush: a sudden switch causes diarrhea that derails weight gain and can dehydrate a small kitten. Keep replacer available alongside solids until 6-7 weeks so weaker kittens still get calories. Once fully on solids, pick one AAFCO 'growth' or 'all life stages' kitten formula and stay with it through the first year -- constant brand switching upsets the gut. Reserve raw only for later, and only as a complete commercial product, never homemade without veterinary guidance.
Key Takeaways
- Weigh kittens weekly; steady gain along the curve matters more than a fixed cup count.
- Begin weaning at 4-5 weeks with thin gruel, thickening over 1-2 weeks.
- Giant breeds need growth food and extra calories until 18-24 months.
- Keep one kitten-formula diet for the first year to avoid gut upset.
- Two missed meals in a kitten warrants a vet call, not wait-and-see.
