0–2 weeksAlmost completely pale
The kitten is born very pale. Warmth, milk, sleep and its mother fill almost everything while the point colour starts to appear.
A Sacred Birman is not the same cat at 3 weeks, 8 months and 12 years. Colour, coat, body, confidence and needs change – and you can see it.
0–2 weeks
3–8 weeksThe world gets bigger
Eyes, points and personality become clearer. Play, handling, people, sounds and cat skills become part of everyday life.
8–14 weeksKitten – still with the breeder
Coordination and confidence grow. The kitten still learns from its mother and siblings and should not be rushed out into the world.
14 weeks–1 yearYoung cat at full speed
A new home, new routines and lots of energy. The body grows, points deepen and the adult coat is not finished yet.
AdultThe adult Birman
More of the finished whole is visible: build, coat, mask and colour. Adult cats still continue to change through the years.
SeniorThe pace may change
Many seniors still play and participate, but may enjoy warmer beds, easier access and closer attention to small changes.
Colour develops – it does not stand still
Birman kittens are born pale. Point colour develops gradually and may continue to change in depth and contrast long after moving home.
