is it that hard to kill rats with mercury, just so stupid can be proven a point.
Ha! One would suspect not (and one would apparently be wrong). What's really mind boggling to me is that it's even still possible to run into people who defend this. Or fluoride, for that matter. If you don't know fluoride and mercury are Neurotoxins at this juncture, even ceiling cat doesn't know how to save you.
