The mistake of "I'll add a little more"
One of the most frequently asked questions by new owners: "How much should my kitten eat?". The intuitive answer ("as much as they want, they are growing") is wrong in many cases. Pediatric overweight is on the rise even in cats, starting from a bad habit: a bowl that is always full during growth.
On the other hand, giving too little slows development, resulting in a small, weak cat with a fragile immune system. The middle ground is a precise formula, tailored to age and weight.
The age chart (medium-sized kitten, normal weight)
The values are indicative: actual needs vary with breed, activity, metabolism. Consider a medium-sized European domestic cat (estimated adult weight 4-5 kg).
- 2-3 months:
- Weight: 0.8-1.4 kg.
- Meals: 4-5 per day.
- Total amount: 120-180 g of kitten pâté or 30-50 g of kitten kibble or a mix.
- Water: always available, wide bowls.
- 3-4 months:
- Weight: 1.4-2 kg.
- Meals: 4 per day.
- Total amount: 150-220 g of pâté or 40-60 g of kibble.
- 4-6 months:
- Weight: 2-3 kg.
- Meals: 3-4 per day.
- Total amount: 180-260 g of pâté or 50-80 g of kibble.
- 6-9 months:
- Weight: 3-4 kg (depending on the breed).
- Meals: 3 per day.
- Total amount: 220-290 g of pâté or 60-90 g of kibble.
- 9-12 months:
- Weight: 3.5-5 kg.
- Meals: 2-3 per day.
- Total amount: 240-300 g of pâté or 65-100 g of kibble.
- From 12 months: gradual transition to adult food, 2 meals per day.
The formula for precise calculation
If you have a non-standard size kitten (Maine Coon, skinny kitten, particularly active individual):
Daily caloric requirement (kcal) ≈ 2.5 × Weight (kg) × 70
Example: 2 kg kitten → 2.5 × 2 × 70 = 350 kcal/day.
Divide the total calories by the calories of the food (indicated on the package, usually 350-400 kcal/100 g for kibble, 80-110 kcal/100 g for pâté).
Pâté or kibble? The three options
- Only pâté:
- Pros: high hydration (78-82% water), digestible proteins, palatability.
- Cons: cost, storage (max 24 h once opened), less effective dental cleaning.
- Only kibble:
- Pros: economical, convenience, satiety.
- Cons: low hydration, risk of overweight from free access, salt and grains.
- Mix of pâté + kibble (recommended):
- 50% pâté, 50% kibble.
- Morning/evening pâté, long hours with kibble in a slow-feed bowl.
- Improves hydration and palatability, dental cleaning.
Kitten food or adult cat food?
Kitten food is formulated with:
- More proteins (35-45% vs 30-35% adult).
- More fats (20-25% vs 15-20%): energy for growth.
- More calcium and phosphorus: for bones and teeth.
- More taurine and omega-3: for developing brain and heart.
Giving adult food to a kitten means:
- Slower growth.
- Weak immune system.
- Possible nutritional deficiencies (taurine = retinopathy, calcium deficiency = weak bones).
Never feed dog food (lacks taurine and arachidonic acid).
Signs that the quantity is right
Appropriate weight:
- Ribs palpable but not visible.
- Visible waist when viewed from above.
- Constant growth of 50-100 g per week until 4 months.
Behavior:
- Plays, sleeps, explores with energy.
- Shiny coat.
- Formed stools, not loose, not overly dry.
- Does not meow insistently for food.
Signs of too much food:
- Swollen belly, "boat-shaped".
- Excessive lethargy after meals.
- Soft/liquid stools.
- Vomiting after meals.
Signs of too little:
- Ribs visible.
- Dull and rough coat.
- Constant meowing for food.
- Lethargy, little desire to play.
The trap of the always-full bowl
Leaving pâté always available = gluttony. Leaving kibble always available = the same: even if the cat is theoretically "self-regulating", many cats tend to be overweight, especially if neutered (they will be in the future).
Better strategies:
- Scheduled meals at fixed times.
- Slow-feed bowl (with obstacles to slow down).
- Puzzle feeders (balls that dispense kibble during play): mental stimulation + controlled portion.
- Leave kibble only during certain hours: 4-5 time windows.
The transition to adult food
At 12 months (sometimes 10 for small cats, 18-24 months for Maine Coons and giant breeds):
- Gradually reduce kitten food over 2 weeks.
- Add adult food.
- Check that weight and activity remain stable.
- Reduce meal frequency to 2 per day.
When to consult the veterinarian
- Persistent thinness despite adequate portions.
- Obesity at 6 months: a specific feeding plan is needed.
- Repeated vomiting after meals.
- Chronic diarrhea: possible food intolerance.
- Slowed growth compared to expected averages for the breed.
The right amount of food in the first 12 months shapes your cat's body for the next 15-18 years. Weigh, measure, observe: a well-nourished kitten is a healthy adult cat, and nothing is more valuable.
