So they can "feel" that something is at 100m instead of 10m? I wonder how they

do that without using sound, or actually moving for the 100m and counting
their

steps... >>

You're right.  I guess they don't have a way to tell exact distances, but
(believe me) they can "guess," I guess you could say, pretty acurately.  They
are definately not in a 2-D world.
