I'm scared of poisons so I just bought a battery-powered device called a Rat Zapper because of a rat problem we seem to be having near our coop. Day One -- one dead mouse. Anyone have any experience with these things? I'm kind of nervous about killing other things -- like squirrels and skunks, but I must say so far I'm impressed with the convenience. Just dump the carcass in the trash - no splatter, no still alive animal, etc.
