Bushtail possums take up to a year of growing before they are old enough to begin breeding, but they certainly make up for lost time. These possums have an incredibly short gestation period, which allows for there to be multiple mating seasons within just one year. There’s typically a smaller birth season in the spring followed by another more productive season in the fall.
Baby possums spend a lot more time nursing than they do in the womb. After spending just over two weeks developing in the womb, a baby possum (a joey) stays in the mother’s pouch for 120 days at a time. 80 of those days are spent permanently attached the the mother’s teat.
