There are many reasons to neuter your male glider, some of the most common reasons are:
1. They are generally less stinky. Not all owners experience a pungent smell but many do. To keep odor down neuter them before their scent glands have time to develop (about 4.5-6 months out of pouch) or a neuter may be done to reduce smell.
2. Some males are less aggressive towards the handler and other cage mates afterwards.
3. The bald spot and other scent glands on the male go away; however, if the male marks often it may reappear.
4. Female gliders can have babies in her pouch, be pregnant, and have a baby outside of pouch simultaneously. Having a glider with joey's can be complicating, sometimes the mother will abandon the joeys leaving the owner to care for it, which is no easy task. Pregnancy is taxing on the body, keeping your animal as pet only will likely lengthen her life span.
Some reasons that some people may not think to neuter a glider:
5. A male will sometimes, especially if he is absent of a female, try to please himself often he can obtain overactive glands, thus leading to an infection that will be expensive to diagnose, treat, and will result in a necessary neuter.
6. They will bark less at night.
7. If a non sexual mature female is placed with a sexually mature male and that male is not neutered there is a more likely chance that the male will try to forcibly mate with the female. The female may then have babies before they can really handle them and a rejected or cannibalized joey is commonly found. If the male is neutered he may try to forcibly mate with the female but there will be no rejected joey.
8. Another reason to lessen occurrences of forced mating is to lower the probability of mating wounds.
