So I went down the kitchen a few nights ago to get something to drink, and was pretty unpleasantly surprised when I saw a rat scurry across the kitchen. Today I bought one of those sticky traps, and within a few hours it had caught the rat.
I went and got a bat, covered it with a bag, and intended to end the rat's "suffering". That was not an immediately popular idea with my wife, who as a Buddhist, believes in the sacredness of all life, including animals. I explained that if I just threw the rat in the garbage, it would slowly starve to death, a fate much crueler than a swift end.
So there is still one more trap up in case my first catch has friends. I hope not.
