Reproduction

The gestation period varies between 93 to 110 days. The mating season occurs typically in the late winter months between December and March, during this time and when the mother is caring for her cubs marks the only times snow leopards are not alone. The mating season is dictated by the harsh winter conditions. Since food is scarce and difficult to obtain during the winter snow leopards wait to mate until late winter which allows them the have cubs during the spring or summer when food is more plentiful. After the male and female mate the male has no other role in the reproduction process. A female snow leopard’s liter can range from one to five cubs; however, the average is two to three cubs. It has been reported that snow leopards in zoos can have as many as seven cubs; this is unusual and if seven cubs wPhoto Credit: Julie Larsen Maher ©WCSere born in the wild it is likely not all cubs would survive due to the mother being unable to find enough food to support all the cubs and herself. When the baby cubs are born they have a full coat of fur and are blind for about a week. However they are helpless until they are six weeks old; during this time they sleep and drink their mother’s breast milk. When cubs are born they weigh between .71 pounds to 1.56 pounds (or 320 to 708 grams) each, after they are born they typically gain around .11 pounds (or 48 grams) a day. It takes both males and females about two years to reach sexual maturity at this time, if they have not already, they will leave their mother and begin life by themselves. A mature snow leopard’s weight is usually between 77 pounds (35 kilograms) and 121 pounds (55 kilograms); however a very large male can weigh as much as 165 pounds (75 kilograms) and a petite female can weigh 55 pounds (25 kilograms). A wild snow leopard’s life span usually lasts 8 to 10 years; while a snow leopard in captivity can live to 18 years old. 

How to get a snow leopard mate?

This is not the only technique snow leopards employ when seeking a mate. They will also produce a soft moan to alert others in the area of the mating season. If they are successful in attracting a mate they will great each other with quiet “chuffing” noises.     

 

What is the relationship like between a mother and her cubs?

After a female snow leopard gives birth to her cubs she nurses them until they are able to photo credit: Julie Larsen Maher © WCSfollow her around outside of the den. Cubs will follow their mother watching her travel her favorite paths and capture food. While following their mother baby cubs will play with each other and their environment, they are very playful and curious creatures at a young age; however they must be careful and the mother snow leopard keeps a close on them since they are vulnerable and may become prey to a larger animal. By nine months old cubs begin to mark their favorite areas this way when they leave their mother around 18 or 24 months they will have established territory of their own. Watch snow leopards mating
