Kittens grow at an astonishing rate -- they double their birth weight in the first week and reach adult size by 12 months. This explosive growth demands specific nutrition that adult cat food simply cannot provide. Getting kitten nutrition right sets the foundation for a lifetime of health.

Feeding Schedule by Age
- 0-4 weeks: Mother's milk only (or KMR kitten milk replacer if orphaned). Never cow's milk.
- 4-6 weeks: Begin weaning -- soft wet food or moistened kibble mixed to gruel consistency
- 6-12 weeks: 4 meals per day. Wet food preferred. Free-feed dry kibble.
- 3-6 months: 3 meals per day. Growth is fastest during this period.
- 6-12 months: 2-3 meals per day. Growth slowing but still needs kitten formula.
- 12 months: Transition to adult food over 7-10 days (large breeds like Maine Coon: continue kitten food until 18-24 months).

Common Kitten Feeding Mistakes
- Feeding adult food: Does not provide enough calories, protein, or calcium for growth
- Cow's milk: Causes diarrhea. Use KMR formula only for orphaned kittens.
- Under-feeding: Growing kittens need more calories per pound than adults
- Sudden diet changes: Always transition food gradually over 7-10 days
- Only dry food: Kittens benefit greatly from wet food for hydration and protein
Frequently Asked Questions
When should I switch from kitten to adult food?
Most cats: 12 months. Large breeds (Maine Coon, Ragdoll, Norwegian Forest Cat): 18-24 months, as they continue growing longer. Transition gradually by mixing increasing amounts of adult food with decreasing kitten food over 7-10 days. Abrupt switches cause digestive upset. If unsure about timing, ask your vet at the 12-month checkup.
