if during day time they would just sleep. night time they will be awake.
but if you give them some food and nice treats, I think ONE DAY will be fine.
Just keep them under 100% LOCKDOWN, do NOT give them a chance to get out by
openning cage, just feed threw bars.
gliders, specially if scared, can be FAST and HARD to handle. so keep
them locked up 100% until in your house.
