The first months of a cat's life are decisive for their development. During this period, adequate nutrition is not just a matter of quantity, but of quality, frequency and composition.
A kitten is not a miniature cat: their nutritional needs are very different from those of an adult. They are growing, developing bones, muscles and organs, and their immune system is maturing. Getting this stage wrong can have consequences that persist for years.
At OnlyFresh you will find feeding options designed specifically to support the growth of younger cats with the finest ingredients.
What does a newborn kitten eat?
During the first few weeks, the only suitable food for a kitten is mother's milk. It contains antibodies, fats, proteins and everything necessary for this very delicate moment.
If the kitten is an orphan or the mother is unable to nurse them, the alternative is kitten-specific formula milk, never cow's milk or milk from other species, which can cause diarrhoea and serious digestive problems.
When do they start eating solids?
The transition to solid food begins between 3 and 4 weeks of age. It is a gradual process:
- Weeks 3-4: Very soft wet food or wet kibble mixed with warm water or formula milk is introduced.
- Weeks 5-6: The proportion of solid food is increased and liquid is reduced. The kitten begins to chew.
- Weeks 7-8: The majority of feeding is now solid. Milk becomes supplementary.
- From 8 weeks onwards: Weaning is considered complete. The kitten can now feed on solid food alone.
The mother usually guides this process naturally. If the kitten is alone, the transition should be even more gradual.
What nutrients does a kitten need?
Kittens have much higher nutritional requirements relative to their weight than adults.
High proportion of animal protein
Cats are obligate carnivores. Kittens need protein of animal origin to develop muscle, the nervous system and tissues. They cannot synthesise certain amino acids such as taurine, which is essential for cardiac and visual health.
Quality fats
These are a concentrated source of energy, essential during growth. DHA fatty acids contribute to neurological development.
Calcium and phosphorus in appropriate proportions
Fundamental for bone development. An imbalance between the two can cause skeletal problems.
Grain-free or with easily digestible grains
Many kittens tolerate excess grains poorly. A diet with a high meat proportion and low in carbohydrates is most in line with their physiology.
How often should a kitten eat?
Kittens have small stomachs and a very active metabolism. They need to eat frequently:
- 3 to 6 weeks: 6-8 daily meals (if in human care)
- 6 to 12 weeks: 4-5 daily meals
- 3 to 6 months: 3-4 daily meals
- From 6 months: 2-3 daily meals
The ideal approach is to gradually reduce the frequency as they grow, maintaining regular mealtimes.
Wet or dry food for kittens?
Wet food
This is especially recommended in the early stages. It provides additional hydration — cats naturally drink little — it is easier to chew and usually has a higher proportion of animal protein.
Dry food (kitten kibble)
Convenient and easy to portion. It is important that it is specifically for kittens — adult food will not do — with high protein, low in grains and without artificial preservatives. It also contributes to dental health.
Combination of both
Many specialists recommend combining wet and dry food to take advantage of the benefits of each option. The proportion can be adjusted according to the kitten's preferences.
Prohibited foods for kittens
There are ingredients that should never be given to a cat, regardless of their age:
- Onion, garlic and leek (in any form): toxic to red blood cells
- Chocolate and caffeine
- Grapes and raisins
- Cow's milk: the majority are lactose intolerant
- Cooked bones: can splinter
- Tinned tuna with salt: can cause long-term kidney problems
- Alcohol and artificial sweeteners
How to transition between foods
When changing brand or type of food, do so gradually over 7-10 days:
- Days 1-3: 75% old food + 25% new
- Days 4-6: 50% of each
- Days 7-9: 25% old + 75% new
- Day 10: 100% new food
A sudden change can cause diarrhoea or rejection, especially in kittens with sensitive digestion.
