Sugar Glider behavior

Question
 We only recently aquired a sugar glider, we rescued it more or less from someone unwilling to care for it anymore. When we got it it was missing a patch of fur on its tail and front of head - but seemed otherwise fine. Today it is shaking, not moving very well, and looks tired, but when we go to fed it, it is eager to eat - what could this mean. It is late on a Saturday night and I'm not sure what vet I could take him to on a weekend is there anything we could do here at home until we get to a doctor.

Answer
as long as he is eating ok he should be ok till at least the weekend is over...if by monday he is still not moving around and is shaking alot I would maybe take him to a vet to get checked to be safe....gliders are usually really active at night so him not moving is not a good thing....
