Quick summary: Kittens need 2 to 3 times more calories per pound than adult cats, divided into 3 to 4 meals daily until around 6 months old. They require kitten-specific food until 12 months. A 3-month-old kitten weighing 2 lbs needs roughly 160 to 200 calories per day. A 6-month-old at 5 lbs needs 250 to 320 calories. Use the age and weight tables in this guide for exact amounts.

How Much Should Your Cat Eat?
Enter your cat's details below for a personalized daily feeding plan, including exact wet food, dry kibble, and meal timing recommendations.
Feeding a kitten correctly is one of the most consequential decisions you make as a new pet owner. The first 12 months of a cat's life set the foundation for bone density, organ development, immune function, and even long-term behavioral patterns. Underfeeding causes stunted growth and developmental deficits that cannot be fully reversed. Overfeeding, particularly in late kittenhood, establishes the fat cell distribution that drives obesity risk throughout adulthood.
The good news is that getting this right is straightforward once you understand what changes at each stage and why. This guide walks through every phase from early weaning through the transition to adult food.
Kitten Feeding by Age: The Complete Timeline
Mother's milk or kitten formula only
Neonatal kittens cannot digest solid food. They need mother's milk or a veterinary kitten milk replacer every 2 to 3 hours. Never use cow's milk, which causes severe diarrhea in kittens.
Weaning begins with wet food
Introduce high-quality wet kitten food mixed with a small amount of kitten milk replacer. Offer solid food 4 to 5 times per day. Kittens learn by smell, so warm the food slightly to enhance aroma.
High-growth phase, 4 meals daily
This is peak growth rate. Organ development, bone density, and immune system formation all accelerate. Feed 4 meals per day of kitten-specific wet food. Do not restrict calories for healthy kittens at this stage.
Sustained growth, 3 to 4 meals daily
Growth continues at a fast pace but slows slightly. Transition to 3 meals per day around 5 months if logistically necessary. Neutering is often recommended around this period, which immediately reduces calorie needs by 20 to 30 percent.
Growth slows, 3 meals daily
Most rapid organ development is complete. The kitten is now building muscle and approaching adult body composition. Three meals per day is appropriate. Begin monitoring weight monthly and adjust portions if gains become excessive.
Transition to adult feeding
Most cats reach physical maturity by 12 months, though large breeds like Maine Coons continue growing until 18 to 24 months. Begin transitioning from kitten to adult food around 10 to 11 months. Continue 2 to 3 meals per day.
Exact Portion Sizes by Age and Weight
| Age | Avg Weight | Daily Calories | Wet Food | Dry Kibble | Meals/Day |
|---|---|---|---|---|---|
| 4 to 8 wks | 0.5 to 1 lb | 80 to 100 kcal | 1 oz per meal | Not recommended | 5 to 6 |
| 2 months | 1.5 to 2 lbs | 150 to 200 kcal | 2 oz per meal | 1 tbsp if mixed | 4 |
| 3 months | 2.5 to 3 lbs | 180 to 240 kcal | 2 to 3 oz per meal | 1 to 2 tbsp | 4 |
| 4 months | 3.5 to 4 lbs | 220 to 280 kcal | 3 oz per meal | 2 tbsp | 3 to 4 |
| 5 months | 4.5 to 5 lbs | 260 to 320 kcal | 3 to 4 oz per meal | 2 to 3 tbsp | 3 |
| 6 months | 5 to 6 lbs | 280 to 360 kcal | One 5.5 oz can | ¼ cup | 3 |
| 9 months | 6 to 8 lbs | 250 to 320 kcal | One 5.5 oz can | ¼ to ⅓ cup | 2 to 3 |
| 12 months | 7 to 10 lbs | 200 to 280 kcal | 1 to 1.5 cans | ¼ to ⅓ cup | 2 |
These figures are starting points for a typical domestic shorthair kitten. Large breed kittens like Maine Coons or Ragdolls should be fed toward the higher end or slightly above these amounts. Small breed kittens like Singapura should stay toward the lower range. Always monitor body condition rather than relying solely on charts.
What to Feed a Kitten: Food Type Guidance
Wet food for kittens
Wet food is the ideal primary diet for kittens, particularly in the first six months. It closely mimics the moisture content of prey, supports hydration during rapid growth, is easier to eat for kittens still developing jaw strength, and is more palatable for most kittens. Look for kitten-specific pate or minced wet food with a named meat as the first ingredient and an AAFCO statement confirming it is complete and balanced for growth.
Dry kibble for kittens
Kitten-formula dry kibble can be offered from around 6 to 8 weeks as a supplement to wet food. The smaller kibble size in kitten formulas is important. Do not feed adult dry food to kittens, as the larger piece size is a choking risk and the nutrient profile is not calibrated for growth. From around four months, you can offer a small measured portion of dry kibble as part of a mixed feeding approach.
Foods to never give kittens
- Cow's milk or cream causes diarrhea and gastrointestinal distress in nearly all kittens
- Raw fish contains an enzyme that destroys thiamine, causing neurological damage
- Onions and garlic are highly toxic and cause hemolytic anemia in cats
- Grapes and raisins have caused acute kidney failure in cats in case reports
- Dog food is nutritionally deficient for cats and lacks taurine, causing heart and eye disease
- Bones from cooked poultry or fish can splinter and cause intestinal perforation
Critical warning about taurine: Cats cannot synthesize taurine from other amino acids. Kittens on taurine-deficient diets develop irreversible retinal degeneration and dilated cardiomyopathy. Always choose AAFCO-certified kitten food and never supplement with homemade diets unless formulated by a board-certified veterinary nutritionist.
How to Tell If Your Kitten Is Eating Enough
Kittens are not great at signaling hunger and fullness the way adult cats can be. A kitten that appears constantly hungry is normal during growth phases. The most reliable indicators are weight gain and body condition rather than behavior.
- Healthy kittens should gain roughly a quarter to half an ounce per day from birth to 4 months
- You should be able to feel ribs easily but not see them when the kitten is relaxed
- A kitten that is listless, not gaining weight, or has a pot-belly may have parasites, which are very common and easily treated with deworming
- Coat quality is a meaningful indicator: dull, sparse, or dry fur often points to protein or fat deficiency
Weigh your kitten weekly in the first 3 months. A simple kitchen scale works well. Consistent weight gain is the clearest confirmation that feeding is on track. Stagnant weight or weight loss in a young kitten is always a reason to call your vet within 24 hours.
The Transition to Adult Food
Switching from kitten to adult food at 12 months is important because kitten formulas have higher fat and calorie density appropriate for growth, but which cause weight gain in metabolically mature cats. Make the transition over 10 to 14 days to avoid gastrointestinal upset.
- Days 1 to 3: 75 percent kitten food, 25 percent adult food
- Days 4 to 6: 50 percent kitten food, 50 percent adult food
- Days 7 to 10: 25 percent kitten food, 75 percent adult food
- Day 11 onward: 100 percent adult formula
The single most important thing about kitten feeding
Do not restrict calories in healthy kittens under six months. The instinct to prevent future obesity by limiting food during kittenhood is well-intentioned but counterproductive. Restriction during peak growth phases causes developmental deficits that persist for life. Focus on food quality, meal frequency, and appropriate food type. Weight management becomes relevant after neutering at around 4 to 6 months, when calorie needs drop by 20 to 30 percent almost immediately.
