If you can't QT now, how did you QT before?
Like I told you before, with 5-6 new snakes coming in at once, I wouldn't risk your resident snakes.
Keeping the racks side by side defeats the purpose of QT.....
I would negotiate with your mother to keep them in the common room or a hallway closet. It's only temporary after all.....
It's not like they're going to be there forever...
Will it be ok?
Maybe. Maybe not.
Ultimately it's your decision whether or not you want to risk your current snakes.
Personally, I wouldn't do that. Especially with the number of new additions coming in....
If I didn't have a QT area, I just wouldn't get any new snakes until I could find an area for it....
