My experience is it's more of a "curiosity" call...
Meaning small Deer have come in from using it, or coyotes.
The other day I had a Doe and a Fawn come into my set-up and leave. I managed to drag them back in twice with the can.
However, they seemed to be more "alert" than relaxed.
So be careful as what to expect, as deer jumping your string is more common after you educate them that something may be out of the ordinary.
They know there home (woods) well!
