So you are looking for a sugar glider? You should look around and try to find homeless ones first. There are probably some nearby. Previous owners will often let them go cheap or free just to get out of the hobby. Older suggies are often more tame and easier to work with and better for kids. Have your males neutered and keep a cage of 2 to 5 members and you'll have a happy, healthy, easy to keep family.
