Feeding a kitten may seem simple, but it is one of the most delicate processes. Common mistakes are often fatal within 24-48 hours. Cow's milk, adult food, irregular meals: let's see what, how much, and when to feed a kitten of every age.
The number 1 mistake: cow's milk
The number one cause of death in orphaned kittens.Why it is deadly:
- Too high lactose content
- Protein imbalance
- Taurine deficiency
- Explosive diarrhea
- Soy milk
- Almond milk
- Powdered cow's milk
What is truly needed
For kittens 0-4 weeks
Specific replacement milk + bottle. Only this.
Calories: 22-26 kcal per 100 g of weight per day.
For kittens 4-6 weeks (weaning)
- Replacement milk (decreasing)
- Soft food: wet kitten food softened
- Water available
For kittens 6-8 weeks
- Wet kitten food (whole)
- Puppy kibble (softened or whole)
- Water available
For kittens 2-12 months
- Specific puppy kibble (not adult)
- Wet puppy food
- Always fresh water
The specific frequencies
0-1 week
Every 2 hours (24/7).
8-12 ml of replacement milk per meal.
1-2 weeks
Every 3 hours.
15-20 ml per meal.
2-4 weeks
Every 4 hours.
20-30 ml per meal.
4-6 weeks (transition)
4-5 meals a day.
Mix of milk + soft food.
6-8 weeks
4 meals a day.
Solid or nearly solid food.
2-6 months
3-4 meals a day.
Puppy food.
6-12 months
3 meals a day.
Gradual transition to adult diet.
The quantities
Milk (orphaned kittens)
22-26 kcal / 100 g weight / day.
Example: 200 g kitten = 44-52 kcal/day = about 35-40 ml of replacement milk.
Divided into meals every 2-3 hours.
Solid food (post-weaning)
Over 8 weeks:
| Weight | Kcal/day | Puppy kibble | Wet food |
|---|---|---|---|
| 500 g | 65 | 20 g | 75 g |
| 1 kg | 100 | 30 g | 100 g |
| 1.5 kg | 130 | 40 g | 130 g |
| 2 kg | 170 | 50 g | 170 g |
| 3 kg | 230 | 70 g | 230 g |
| 4 kg | 280 | 80 g | 280 g |
Puppy kibble contains about 380-400 kcal/100g. Wet puppy food 90-100 kcal/100g.
Errors to avoid
Error 1: cow's milk (NEVER)
As stated before, I repeat: deadly.
Error 2: canned tuna
Never as a diet. Only occasionally as a treat:
- Too much salt for kittens
- Uncontrolled mercury
- Causes nutritional deficiencies if constant
Error 3: adult food
Lacking in calories, proteins, DHA, specific taurine for growth.
Result: stunted growth, weak immune system.
Error 4: giving too little food
Kittens need double the calories per kg compared to adults.
Error 5: irregular meals
Without routine, blood sugar spikes, especially in small breeds.
Error 6: raw food for infants
They do not have adequate digestive enzymes. High health risks.
Error 7: insufficient water
Puppies dehydrate easily. Always have fresh water available (even if they drink milk).
Error 8: sudden changes
From milk to kibble in 2 days → diarrhea.
Transition 7-14 days.
The temperature of food
Milk:
- 38°C (body temperature)
- Hand test (not wrist): warm but not hot
- Never heat in the microwave (hot spots can burn)
- Bain-marie preferred
Solid food:
- Room temperature or slightly warmed
- Never cold from the fridge
- Never boiling hot
Signs of proper nutrition
Good:
- Eats with appetite
- Gains 10-15 g per day (infants) or 50-100 g per week (weaned)
- Round belly, not bloated or sunken
- Shiny coat
- Normal energy
Bad:
- Refuses food
- Vomits
- Diarrhea
- Lethargy
- Belly bloated or sunken
- Stunted growth
→ Veterinarian.
The supplements
For orphaned kittens in intensive care:
- Caloric paste (Nutri-Plus) if underweight
- Probiotics if diarrhea
- Multivitamin for puppies
Only on veterinary advice.
Weaning
See dedicated article. Week by week:
- 3-4 weeks: first soft food
- 5 weeks: softened kibble
- 6 weeks: whole wet food
- 7 weeks: whole kibble
- 8 weeks: weaned
Adopted cats at 2-3 months
Probably already weaned. Continue with:
- Puppy kibble for a total of 9-10 months
- Wet puppy food
- 3-4 meals a day
The water
- Always available
- Change twice a day
- Ceramic or steel bowls (never plastic)
- Water fountain helps puppies drink more
Final advice
Feeding a kitten correctly is the foundation of its future health. Specific milk for orphans (never cow's milk!), frequent meals for age, gradual transition, specific puppy food. The most common mistakes - cow's milk, adult food, irregular meals - are often fatal. Investing an extra €5-10 in quality puppy food saves lives and builds a healthy cat for 15-20 years.
