* Opossums are marsupials: This means they have a pouch where their young develop after birth.
* "Possums" is sometimes used incorrectly: People sometimes use "possums" as a slang term for possessions, but that's not what you're asking about here.
So, to answer your question more directly:
* Both boy and girl opossums have pouches. This is a characteristic of all female opossums, not just males.
* Only female opossums use the pouch to raise their young. Male opossums don't have a role in caring for offspring beyond mating.
