What Is the Average Siberian Tiger Life Span?

The life span of Siberian tigers varies depending on whether they are raised in captivity or live in the wild; wild Siberian tigers can live to be 10 to 15 years old, while those raised in captivity can live to be 20. Many factors contribute to the longevity of these tigers, including their access to food and water and the presence or absence of disease and biological defects within a given population.

Siberian tigers spend much of their lives alone: males and females may spend time as couples for brief periods during the mating season, but upon conception, go their separate ways. Female tigers generally produce two to three cubs at a time, and the survival of those offspring depends on many external factors, including the availability of food and water and the conditions of the surrounding environment. In a good year, all offspring may survive and will remain with their mothers for two or three years before leaving to find territories of their own. Tigers raised in captivity generally enjoy longer life spans than their wild cousins because they have access to abundant sources of water and food and lack manmade and environmental threats, such as land conversion and natural disasters, that would jeopardize their existence in their native habitats.
