Kitten Age- Quick Guide to How to Tell the Age of a Kitten

Birth: At birth kittens usually weigh between 80 – 100 grams
  • New born 0 – 3 days: The umbilical cord is still attached, eyes are closed and ears are folded. Nose and paws may be pink in colour. The kitten is unable to see or hear
  • 7 – 10 days: The eyes & ear canal begin to open
  • 2 – 3 weeks: The kitten begins to stand, the eyes and ears open fully. Eyes will be baby blue and ears will appear small and rounded
  • 4 weeks: The kitten begins playing and exploring its environment
  • 5 weeks: The kitten should be fairly confident on its feet by this age
  • 6+ weeks: Kittens are extremely active. The adult eye colour will begin to emerge


    Teeth are also a good way to determine age

    Baby teeth

    • 2 weeks: Deciduous or milk incisors (the small teeth at the front) begin to come in
    • 3 – 4 weeks: Deciduous or milk canines (the long, pointy teeth next to the front teeth – incisors) begin to come in
    • 4 – 6 weeks: Deciduous or milk pre-molars (also known as bicuspids, these are the teeth located between the canine and molar teeth) begin to come in
    • 8 weeks: All baby teeth have come in

    Adult teeth

    • 12 – 16 weeks: Incisors come in
    • 4 – 6 months: Canines, pre-molars & molars come in
    • 7 months: All adult teeth should be fully developed
