You won t hear this sound very often once they get used to you as you learn their likes and dislikes. The third sound is a small, quieter chirp, which is simply a noise they use to communicate with each other. The fourth noise is a loud sharp barking. This noise indicates that the sugar glider wants attention from either another glider or its owner. This last noise can be quite annoying as it is surprising loud for such a small animal, and as it often occurs late at night, it tends to awaken the humans in the house.
Sugar gliders give off two types of odors.
The first is the smell of their wastes, and you can control this one by keeping their cage clean. They also give off a very distinct odor when mating, and while it isn t unpleasant, it can be overpowering for a week or two. As with many nocturnal animals, sugar gliders have a great sense of smell, which they use to identify humans and other sugar gliders. It doesn t take long before a sugar glider is able to identify its owner s particular smell. The male glider has two scent glands that he uses for marking his territory.
