What age do cubs leave their mum?

Cubs typically leave their mother at around 1.5 to 2.5 years of age, depending on the species. For example, bear cubs often stay with their mother for about 2 years, while big cats like lions may leave after 1.5 years. This period allows them to learn essential survival skills before becoming independent. However, the exact timing can vary based on environmental factors and the availability of resources.
