Their reproduction:
Kangaroos have no set breeding cycle and are able to breed all year round as long as they have access to water and food. Kangaroos give birth to baby Joeys. The babies Joeys are very tiny and hairless.  The mother’s pouch has four teats from the Joey’s live and they drink milk until they can survive in the outside world. Kangaroos can also delay the process of pregnancy up to 12 months and normal gestation is around 35 days.
