Proper nutrition during kittenhood lays the foundation for a lifetime of good health. Kittens grow rapidly during their first year of life and require a diet rich in high-quality protein, healthy fats, vitamins, minerals, and calories to support healthy development.
Most kittens are considered kittens until 12 months of age, although some large breeds, such as the Maine Coon, may continue growing until 18–24 months.
Important: Feed a diet specifically formulated for kittens. Adult cat food does not provide the nutrients needed for healthy growth and development.
Proper nutrition supports:
🧠 Brain development
💪 Muscle growth
🦴 Healthy bones and teeth
🛡️ Immune system development
❤️ Heart health
👀 Healthy vision
✨ Healthy skin and coat
⚡ Energy for growth and play
Good nutrition during the first year helps reduce the risk of nutritional deficiencies and supports lifelong health.
Cats are obligate carnivores, meaning they require nutrients found primarily in animal tissues.
Recommended Amount
30–40% protein (dry matter basis)
High-quality protein sources include:
Chicken
Turkey
Fish
Beef
Eggs
Protein supports:
Growth
Muscle development
Tissue repair
Immune function
Fat provides concentrated energy needed for rapid growth.
Recommended Amount
18–25% fat
Healthy fat sources include:
Chicken fat
Fish oil
Salmon oil
Healthy fats help support:
Brain development
Vision
Healthy skin
Shiny coat
Energy needs
Unlike many other animals, kittens require several nutrients that must come from their diet.
Important nutrients include:
Taurine
Arachidonic acid
Vitamin A
Vitamin D
Niacin
These nutrients support:
Heart health
Eye health
Nervous system development
Normal growth
Growing kittens need balanced calcium and phosphorus for proper bone and tooth development.
A complete commercial kitten food provides these nutrients in the correct proportions.
Do not add calcium supplements unless recommended by your veterinarian.
Fresh water should always be available.
Hydration supports:
Kidney health
Digestion
Body temperature regulation
Overall growth
Many kittens benefit from eating a combination of canned and dry food to help increase moisture intake.
Because kittens have high energy needs, they should eat more frequently than adult cats.
Nursing from their mother or kitten milk replacer
Feed every 2–4 hours if bottle-feeding
Begin weaning onto wet kitten food
Offer 4–6 small meals daily
Feed 3–4 meals daily
Feed 2–3 meals daily
Your veterinarian can help determine the best feeding schedule for your kitten.
Look for foods labeled:
✅ Complete and Balanced
✅ Growth or All Life Stages
Choose products that meet AAFCO nutritional standards for growth.
The first ingredient should be a named animal protein such as chicken, turkey, or salmon.

Purina ONE Healthy Kitten
Purina Kitten Chow
IAMS Healthy Kitten
Fancy Feast Kitten
Hill's Science Diet Kitten

Both can be part of a healthy diet. Wet food provides additional moisture, while dry food can be convenient and may support dental health. Many veterinarians recommend feeding a combination of both when appropriate.
