All gliders can have a scent, some of it depends on the diet you feed. A lot of it depends on how clean YOU keep their cage and area. They pee everywhere and anywhere, so you have to keep up with it.

I am not sure about females being less territorial or not, but an un-neutered male will tend to be more aggressive than a neutered male or a female. Maybe others can chime in here.

Do your research now, know what you need, have a diet you want to go with, make sure you know the commitment before you buy any gliders.

Research is your friend.
