We have plenty of squirrels in the immediate neighborhood; they'll do for fricasee. An air rifle, wrist rocket slingshot or scoped and silenced .22 pistol seems to be a usable tool for such purposes hereabouts.
Over the run of a couple of months or so, as could happen during an extended snowstorm series, flooding, or in the aftermath of a major earthquake, I'd rather have the kitties around to clear up local rodent populations. Particularly rats.
