Kitten Care Guide

Two of the first questions caretakers ask about a new litter: how old are they, and are they male or female? These charts help you find the answers.

How old is that kitten?

A kitten’s age determines almost everything about its care — whether it needs bottle feeding, how often it eats, and when it’s ready for spay/neuter surgery. Use the milestones below to estimate age, then match it against the detailed progression chart.

  • 0–1 week: Eyes closed, ears folded, umbilical cord may still be attached.
  • 1–2 weeks: Eyes beginning to open, ears still folded.
  • 2–3 weeks: Eyes fully open (blue and unfocused), wobbly on their feet.
  • 3–4 weeks: Incisor teeth emerging, more stable, ready to explore a litterbox.
  • 4–5 weeks: Canine teeth emerging, eyes focusing, more confident.
  • 5–6 weeks: Premolar teeth emerging, ready to start eating wet kitten food.
Quick reference: kitten development from newborn to six weeks.

Week-by-week progression from newborn to ten weeks.

Is it a boy or a girl?

Determining sex can be tricky, especially with very young kittens. The key is the distance between the anus and the genital opening — it is longer in males and shorter in females. The diagrams below make it easier to compare.

Adult cats: males have a greater distance between openings than females.
Kittens: in males the openings resemble a colon (:); in females, a lowercase i.

When in doubt, don’t stress — a veterinarian will confirm sex at the spay/neuter appointment. If you’re raising a litter and need help, please reach out to us.
