Well, even though I rigged the ceiling with plywood, Graemer is still trying to get into the drop ceiling. Now he is looking at the planters hanging from the ceiling...and is trying to go up the cotton curtains to pop a tile! So the room is closed off for the time being until I figure out what I can do about it. I suppose I will need to remove the drop ceiling and fix the existing ceiling in a hurry. I think the smell (old I hope) or scent of mousies is still up in the upper part of the ceiling. Yikes. He thinks of nothing else when I am with him in this room. Well, food does distract him a bit. What a pain in the neck this is becoming for me.
