Get a cat.
Mouse shit or cat box.. I hate both options.
I wish I had rats or mice to kill, im getting bored of throwing my roommates' cat into our pond for fun.
One of the more inventive things I've seen was as follows: Catch four mice. Take three, pet them, feed them 3x daily, give them a warm, comfortable place to sleep. Take remaining mouse, feed it nothing but Beefcake 3000 and Ripped Fuel, and keep it in total darkness for 2-3 weeks. Invite friends over, take bets, and place all four mice into an arena of death. Enjoy.
Get the shocker trap already. They won't even have the opportunity to steal the bait.
