袋鼠的繁殖季节多种多样。 复制全年都在进行，但澳大利亚12月到2月的夏季是最常见的。 雄性袋鼠可以弯曲肌肉以吸引雌性，并且可以争取与雌性繁殖的权利。 女性通常生产一只小袋鼠，叫做乔伊。 在浸泡后，袋鼠会在妊娠期超过一个月（约36天）后生下宝宝。 婴儿joey重约0.03盎司，出生时长度不到1英寸，大约相当于葡萄的大小。 出生后，乔伊将用它的前肢穿过它的母亲的皮毛到她的小袋，在它的生命的最初几个月里它将保留。 五到九个月后，根据物种的不同，乔伊通常会在短时间内离开小袋。 大约九到十一个月后，乔伊将永远离开母亲的小袋。
The breeding season of kangaroos is varied. Replication is ongoing throughout the year, but Australia’s summer months from December to February are the most common. Male kangaroos can flex muscles to attract females and can fight for the right to breed with females. Women usually produce a small kangaroo called Joey. After soaking, the kangaroo will give birth to the baby after more than one month (about 36 days) of pregnancy. The baby joey weighs about 0.03 ounces and is less than one inch in length, about the size of a grape. After birth, Joey will use its forelimbs to pass through the mother’s fur to her pouch, which will remain in the first few months of its life. After five to nine months, depending on the species, Joey usually leaves the pouch in a short time. After about nine to eleven months, Joey will leave his mother’s pouch forever.
