We have had similar experiences with different noises. My son's father
has a bunch of different animal calls. One day he was playing with one,
and it was making the ferrets crazy. One of them came up and bit him on
the arm! I felt he had it coming to him for teasing, but he did not see
it that way! :)
Instinct tells them that mice, etc make that noise and to go after it.
