How many offspring do tree kangaroos produce and how often?

Kangaroos do not have litters.

Kangaroos commonly give birth to just one joey at a time, but twins have been recorded.

Female kangaroos of reproductive age are in an almost constant state of pregnancy. They have the ability to indefinitely suspend the development of an embryo (called embryonic diapause) until conditions are right for it to be born, e.g. there is enough food to support an increase in the population.

Kangaroos can also have two joeys of differing ages at one time

• one in the pouch, and one almost grown one. The mother kangaroo

is able to produce two diffferent kinds of milk to meet the nutritional needs of each one.
