Will my sugar gliders attack my flying squirrel?

Well, I want to flyer proof my room to let my flying squirrel run around a little bit and I have every things done and ready but I'm afraid my sugar gliders will attack my flying squirrel through the bars. My flying squirrel is very cuurious and has jumped on the cage before but they were eating and didn't notcie him. I don't have a blanket big enough to cover the whole cage and my flyer is healing from hind leg paralysis. he can walk again but he needs t build up strength in them so he may not be as fast as regular flyers. PLEASE HELP ME! I NEED AN ANSWER QUICK! WILL THEY ATTACK HIM AND IF SO, THEM HOW DO I PROTECT HIM FROM THEM WITHOUT MOVING THE CAGE??????????
