Life Cycle

Young squirrels are born blind and they do not have any fur on them. They weigh 13-18 g (0.4-0.6 oz). They start growing fur when they are around 18 days and start opening their eyes during 26-36 days. The mother starts weaning them when they are 6-9 weeks old and it continues for more 3 months. During 4-6 months of age, they become young but stay with their families. They become adult attaining sexual maturity when they reach 8-9 months.
