re: Something in the attic - any suggestions?

I recently dispatched a rat that decided the cold weather meant it could move in. Are you aware that they now make Rodent Electrocution Chambers of Death(tm)? I wasn't, but I am now. Rat goes into chamber for some delectable peanut butter. Chamber senses rat. Rat rides the lightning. No mess, no poisoned animal to hide in the walls to die, no pissed off and scared half dead rat caught in a trap just screaming until you bludgeon its rodent brain into oblivion. Just 'bzzzzzz' (if anything) and you have a dead rat.

Maybe they make a larger model for possums and stuff like that!
