Ha - cat's tails - I remember seeing an old cow casually step down on a barn cat's tail. The cat was shrieking it's head off, scratching, clawing and spinning his wheels, and the cow paid no mind. Dang near pinched the tail off, in fact, the cat moped around for a week or so with this dead thing dragging around behind, and we finally caught it and clipped it off - and then the cat perked right up and back to normal.
I bet that pump belt would get them too, only quicker. . .
