I have been designing a mousetrap for two years. I have a few posts regarding this. I have kept experimental mice in the process. Some have died. Some have become pregnant and died. Some have been killed by idiots that I have allowed into my house. But I love this one. Having spent many hours whith her, I love her. I also have a rat in my house. I do not love this rat. I tried to trap it with my trap, but it is clever. In the proccess of refining my trap, the rat escaped from my trap. It now knows not to enter my trap. As they say, "the best layed plans of mice and men". Now what?
