They are definitely mischievous little things. Kino (not in any of the pictures) was an eraser thief and he hated for anyone to find his stash. I once found his eraser stash under the bed and he went right to work taking each eraser to a new location.
LOL @ stealing fruit loops!
We had moved once and were in the process of "ferret proofing" the house. Well, Thatcher, showed us that we hadn't done a good job because he managed to get into the heat vents. Getting him out was quite a chore.
