Tex, I'm afraid that would put me over the edge. I've been thinking about getting a good hard shooting BB gun or pellet gun. It probably wouldn't kill them, but it might make them think twice before they showed up around here again. Since I'm in town, I can't shoot firearms. My dog loves to chase them, but seldom catches one. But he sure scatters them when he goes outside.
Here is my "squirrel dog/Frisbee dog, Bo, an Australian Shepherd.
