Mary Sue's mention of a squirrel being accidentally electrocuted reminded me of another gardener's approach to a varmint (American for "vermin") problem. Possums (American for "opossums") were damaging the plants in his garden pond, so he strung a wire around it at possum height (they don't jump as far as we know, and they're really stupid) and ran a slight current through it. No more destroyed pond. You can get all sorts and strengths of electric animal deterrent devices, from the plastic-webbing-embedded wire used around horse paddocks to little mats meant to keep your cat from jumping on the kitchen counter. If I were better at tech stuff, I might experiment in that direction, but I don't have power out to my bulb collection at present. Jane McGary
