Yes, Heinz brought me not 1 but 2 voles on Saturday. This morning he brought me a field mouse. And specifically showed it to me in case I would miss the quivering little thing on the floor between me and my computer. Of course when I went to get something to pick up the little thing it was gone only to be found later on the floor next to my shorts. It is safely outside. And Heinz has gone back outside. Sigh. http://en.wikipedia.org/wiki/Vole .
