I have one of those plastic igloos with the flat top that Sugar just
loves to play in.  However, Zo likes to move it to the plexiglass barrier
and use it as a launching pad to get over the barrier.  As a result,
we've had to keep it upside-down all the time, which upsets Sugar.  There
are four holes in the top, so I was thinking we could run something
through the holes and secure it to their cage, then Zo couldn't move it
around, and Sugar would have her igloo back.  But I'm not sure what we
should use.  I'm afraid they would hurt thenselves if we used fishing
line or thread, and I think if we used string, twine or yarn, they'd
chew on it and get a blockage.  Any ideas on what we could safely use?
