It is important for sugar gliders to be kept in pairs and if they are not they can experience depression, they normally lose their appetite and can die of starvation! The owner would have to play with them for hours a day which no one has the time to do these days. The way to make your sugar glider happier and keep your mind focused on your studies is to get another sugar glider! In the wild the travel in large colonies and they are very social creatures making it hard for them to reject other sugar gliders. After I introduced my sugar gliders they were friends for life and never left each other side.
