They will be fine in the cage for the duration of your trip.
I have been away for a week and will not get back until next Tuesday.
When I am out of town my son feeds the gliders but does not take them out of the cage. He feeds them a bit earlier than I usually do to make sure they are still sleeping and less likely to jump out the door of the cage like the sometimes do with me.
He is not fond of wrangling escaped gliders but has had to do it a time or two in the past when he fed them after they were awake.
They are just extra happy to see me when I get back and ready for play time.
Do add some new toys to the cage for them to explore before you leave. If you use small toys like straws, monkeys, plastic bracelets or army men that can be just put on top of the cage for them to pull in at night, your caregiver can just gather the toys up from the floor of the cage and put them back on top each morning when she removes the dishes and left over food.
My gliders never seem to get tired of throwing toys all over the cage.
