Yearling

Male and female meerkats reach maturity around the age of one year. The female’s first oestrus seems to occur around the age of one year, though this is rarely observed. They often do not become pregnant until the age of two years, or else they abort, or their litters are killed by older females. However, early pregnancies occur – the youngest female to give birth was 9 months old. After reaching maturity, male meerkats start to join roving expeditions, often led by older, experienced males.
Yearlings also start to contribute to common tasks in the group, like babysitting or performing sentinel duty. Adult meerkats weigh approx. 600-800 g, but the maximum weighed for a non-pregnant meerkat was 1017 g.
