Hi, i am the proud owner of a male sugar glider, his name is Marco. my question is, should i get him a sugar glider companion, or will he be O.K. by himself. I carry him with me all day, but i'm not sure if that's enough. I have heard that no matter how much time you spend with a glider,it will never replace the companionship of it's on kind.I just don't want him to die of loneliness.How will i know if he is happy?
