There are some definite unique differences between male and female sugar
gliders. The choice on which sex may be better as a pet depends on an
individual's ownership choices and the type of community of sugar
gliders they'd like to set up.
The females are certainly true to their marsupial nature by the fact
that they have a pouch. The pouch is a small area in the center of
their belly where the young are able to migrate to and then they're
raised in the pouch. They do continue to have the pouch throughout life
even if they never breed or if they ever reproduce. Telling the
difference between the male and female is often pretty easy as the males
do have a unique testicular structure that makes it pretty obvious to
know that they are boys. They have what almost appears as a pendulous
small sack that is in the lower part of the belly that is the structure
that houses the testicles.
The housing of sugar gliders doesn't really matter, as both opposite sex and same sex pairs and groups does work well in captivity, although it is recommended that you have males neutered in order to prevent reproduction and prevent the development of a large colony of them. It's thought to help with hormonal levels and making them a bit more social, a little more laid back, makes them a bit less temperamental, less testosterone driven aggressive. I think it works better if animals are living in community and somebody chooses to have multiple sugar gliders that they have any of the males neutered to keep more of a peaceful environment for them. We definitely believe that two or three males that live together should all be neutered as well.
There aren't many differences between males and females as far as whether they tend to be more social, whether they tend to be more friendly. If you talk to enough different people, they often have different experiences based on the sex of the sugar gliders they have owned, but we haven't found that owning a male versus a female or a pair
of males or a pair of females really makes a difference in how social there are. Both males and females do require equal amounts of proper socialization, attention, and an appropriate diet.
So whether you choose to own and have a specific preference for either
of the sexes, males and females both equally make great pets. We do
recommend never having only one sugar glider. They do well at least in
pairs or in small groups. And remember, same sex pairs can live
together peacefully and it's always important, to ensure that, that you
have the males neutered.
