I don't blame any of our critters for responding to their instincts.
Our greyhound, Icabod, had absolutely no prey drive. When we lived "down south" (for us, 180 miles south of Chicago is down south), we were out in the boonies on 17 1/2 acres. On one occasion, Roy unknowingly mowed over a rabbit nest. Icabod found the nest with the baby bunnies and he was literally nuzzling the bunnies. On another occasion (the acreage was completely fenced with barbed wire), a fawn apparently could not finish its jump over the fence and was caught on the barbed wire. Icabod never even noticed the deer. Roy was able to free the fawn from the fence and in payment for his good deed he was kicked in the face (we know it wasn't done on purpose) and his glasses went one direction while his cap went in the other direction. How many people do you know that have been kicked in the face by a deer?
Now Taffy was a world class mouser. One night we were watching tv and I was half asleep. For whatever reason I woke up and there was Taffy with something wiggling in her mouth. In my daze, I realized it was a mouse and screamed. Taffy dropped the mouse, it ran, and Taffy was in hot pursuit.
When we lived south of Madison (Wisconsin), we lived on a 1/4 corner lot that we fenced in. We put a bird feeder in the yard a fair distance from the back door. Rhett would go out that door full tilt and get songbirds and drop their dead bodies at my feet. It happened so fast (and only twice before we moved to feeder outside the fence) that there was no way to stop him.
Our critters are predators as much as we are. Every fall we are out deer hunting and if those turkeys keep coming to the bird feeder they may be our Thanksgiving dinner this year.
