Then, go to the Home and Garden show and pick up a cat. Or go to the humane society. I don't know how they knew, but the Grapple Cat has been just like they told me, and he was picked up off the street somewhere. He killed all the mice in the shop, and keeps it mouse and vole free. He doesn't take on packrats though. He does try to take down The Used Dog once in a while with the classic style of lions--grabbing the flank of the intended meal to bring it down. The Used Dog is a bit too big for that so no worries. Oh, and every once in a while, I find a freshly killed put in the middle of the road for my viewing pleasure. He's been well worth the $40 I had to pay for him.
