I've got a situation where a neighborhood domestic cat has selected my yard as his crapper. I was thinking of a co2 pistol to see if I could have the cat reconsider his toilet location. I don't want to kill, maim or wound the cat, just change it's crapper GPS location. I've never owned or even shot a co2 pistol, would this be overkill for telling a crapper-cat he's got mail? Are they accurate enough so a butt shot hits the butt and not the eye? I've got three dogs but even with an in-progress dump this cat can pinch a loaf and make the fence before they get him. He actually seems to enjoy the chase.
