Most kangaroos are able to breed all year round. Female kangaroos have two vaginas, or what are called paired lateral vaginae. These are for the purpose of transporting the sperm to the womb, but there is a midline pseudovaginal canal for actually giving birth. Male kangaroos have substantial penises that are used in the same fashion as with other species, but unlike most species of marsupial, they do not have a bifurcated penis. Female kangaroos can often be in a state of almost permanent pregnancy, with an embryo "suspended" until the mother's body is ready to release it - whether that be when another joey is sufficiently weaned, or feeding conditions have improved.
The gestation period lasts 31-36 days. Baby kangaroos are the size of a jellybean when they are born. They are born blind and hairless. A baby kangaroo is born from the female's uterus and then climbs up the outer fur of the female and into the upward facing pouch where it attaches itself to a nipple until it becomes stronger. The mother kangaroo licks a path to the pouch to help guide the joey. Baby kangaroos live in their mother's pouch and feed by drinking milk. The teat swells in the joey's mouth, securing it in place so it cannot be accidentally dislodged. The joey will usually stay in the pouch for about 6-9 months until it is developed enough to leave the pouch and move about independently.

∙ 12y agoto breed the black bear first sniffes its mates butt then start to hump the other one until its private part inserts into the other bears and the sperm leaves it and then the baby bear grows inside the humped bear until it comes out where the privates went in. also same with humans, but humans enjoy it a lot lot lot lot more and can use things to prevent the baby from coming even after the penis goes into the vagina.
