After a gestation periol of 98 - 104 days 1 - 5 cubs , commonly 2 - 3, are born in a den. They are born helpless and with their eyes closed , opening their eyes within 7 days. At 2 months old the cubs are eating solid food and at 3 months old they begin to follow their mother around.The cubs stay in the company of their mother until they are between 1 and 2 years of age after which they leave to find their own territory.Females become sexually mature at 2 - 3 years of age while males reach sexual maturity at approximately 4 years of age. Snow Leopards mate between January and March and after mating the pair go their separate ways, with the female preferring to do all of the parenting herself. Due to the length of time the cubs stay with their mother, Snow Leopards mate every other year.
