Don't forget that the glider is nocturnal. Sugar Gliders cannot be outside in the direct sun. The sun will injure their eyes severely. Cages need to be good sized. They can be bought or home made.
Homemade cages are relatively easy to build.
The cage should be weld wire because sugar gliders like to climb. The size of the mesh needs to be small. Bigger is better. Place live fruit tree branches in their cage, and replace them frequently. The other reason they need to chew to keep their teeth healthy.
