Well I myself made the mistake of just having one glider for a long time and finally got mine a friend. Luckily mine did not self mutilate or over groom but I do not think she was as happy as she should have been. I would advise for you to get your sugar glider a buddy

he will be a happier glider because w/o a friend it could result in depression. Honestly, I think this rule should go for any pet, not just sugar gliders. Get your pal a friend. This is a little off the topic of suggies, but I got a puppy a couple of years ago and me and my husband work full time so she was all alone for the first couple of months during the day and she started to destroy things out of boredom.I got her a friend a year later and she was much better! Two are always better than one.
