I typically feed them a special recipe of LR22.
I don't particularly like doing that.
I don't mean like I don't like doing dishes, because killing an animal comes hard to me, because I respect life. But I do it because it's a chore that needs to be done if I want to eat, just like tilling the garden or weeding.
To kill a creature that is not food, or is not a threat, or a pest, is morally wrong. God gave us dominion over the animals, plants and fish for more than wanton destruction.

Perhaps Snopes could reveal the about that rumor?
Dahmer? Is that you?
