The female takes full responsibility of raising cubs. She is pregnant for 93-110 days and 2 or 3 cubs are born, usually in June or July. To give birth, female snow leopards find sheltered den sites.
A snow leopard grows quickly: Cubs are small and helpless when they are born, and do not open their eyes until they are about 7 days old.
At 2 months old, cubs are ready to eat solid food.
At 3 months old, they begin following their mother and start to learn important behavior like hunting.
At 18-22 months old, cubs become independent of their mothers.
In captivity, snow leopards have been known to live for as long as 22 years. Life in the wild is much harder, so they die younger. It is known that Snow Leopards can live up to 13 years old.
