how often to feed newborn kittens

Newborn kittens need to eat very frequently, day and night, and the schedule changes quickly as they grow.

Quick Scoop: How often to feed newborn kittens

If the kittens are under 4 weeks and not nursing from mom, use kitten milk replacer (KMR), not cow’s milk.

By age (bottle‑fed or weak nursing)

  • 0–1 week old (0–7 days)
    • Every 2–3 hours , including overnight (8–12 feeds per day).
* Stomachs are tiny, so feeds are small but very frequent.
  • 1–2 weeks old
    • Every 3 hours or so , still overnight (about 8 feeds per day, many guides say 5–8).
  • 2–3 weeks old
    • Every 3–4 hours (about 5 feeds per day).
  • 3–4 weeks old
    • Every 4–6 hours (about 4 feeds per day).
* You can start offering a little slurry of kitten wet food plus formula as they get closer to 4 weeks.
  • 4–6 weeks old
    • 3–4 meals of canned kitten food per day; some still get a bit of formula as they wean.
  • 6–12 weeks old
    • About 3 meals a day of kitten food, wet or a mix of wet and dry.

Key safety tips you shouldn’t skip

  • Use kitten milk replacer , never cow’s milk (can cause diarrhea and dehydration).
  • Feed kittens on their bellies , not on their backs (reduces risk of aspiration).
  • Keep them warm ; cold kittens can’t digest well and shouldn’t be fed until gently warmed.
  • Weigh daily; healthy kittens usually gain about 15–20 g per day (roughly 0.5–0.75 oz).
  • If a newborn kitten won’t eat for more than one feeding , cries constantly, or feels cold or limp, that’s an emergency — call a vet or emergency clinic right away.

Little “real‑life” example

Imagine three 3‑day‑old orphans: they’d be on a schedule like 2–3 ml of KMR every 2–3 hours around the clock , weighed daily, stimulated to pee/poop after each feed, and kept in a warm, draft‑free box with a safe heat source. As they move toward 3–4 weeks, you’d space feeds out to every 4 hours, then gradually swap bottles for a shallow dish of formula and soft kitten food.

Mini FAQ

  • What if mom is nursing?
    If mom is healthy and attentive, she usually handles feeding; you mostly monitor weight gain and only supplement if kittens are crying, underweight, or pushed away.
  • Can they overeat?
    Bottle‑babies can aspirate or get tummy upset if overfed too fast, so use the right nipple size, let them suck at their own pace, and stop when their belly feels comfortably full, not hard.

TL;DR: Newborn kittens eat extremely often — about every 2–3 hours in the first week, slowly stretching to every 4–6 hours by 3–4 weeks, then transitioning to 3 solid meals a day as they wean.
