I usually use Victor snap traps, but I thought that having a repeating trap would be handy.  I loaded the Tin Cat with the same bait I used on this round (which happened to be marshmallows), and I also put in some poisoned mouse bait; I don't think that a live mouse trap is remotely useful, since dropping a semi-domesticated animal (they are HOUSE mice, folks) out into the wild is none too humane, and in fact in my state it is illegal.  And I just want them dead, thank you.
