My single-mother nextdoor neighboor once came home to a feral cat in her basement and frantically called me up for help. It had obviously used the Kitty-Door that her two cats use to get into the house. We live out in the boonies and Animal Control is a joke. When we called them they told us to lock him in the basement and they MIGHT have someone out to her place the next morning. Like she could sleep with this thing howling in her basement!
We tried for hours to get a blanket over the little bugger so we could wrap him up and get him out of there. He was too fast and way too nasty. Once he finally took a chunk out of my wrist, I got hopping mad. I couldn't use a firearm safely because we were, after all, indoors and I thought a bludgeon or club would probably piss him off even more unless I scored a lucky blow to his head.
I told my neighbor to wait a second and went next door to retrieve my katana. I sent everyone upstairs and one clean cut was all it took to separate head from kitty.
All was quiet, FINALLY, as I walked up the stairs. My neighbor and her 8 year-old son were sitting together on the sofa under a big blanket that they had pulled up to their chins. He looked at me, and then the sheathed katana, and said, "Mom, do cats go to Heaven?"
We busted out laughing which, after the several hours of tension, was a much needed relief.
My Iaido instructor just said, "One cut, one kill" and smiled when I told him about it.
my brother cat was left with him once....when he came back the cat did the EXACT SAME THING minus the dieing part. down to the CRAPPING. 
needless to say he was kicked out SOON after, and he THINKS the poor cat got into this jerks stash...so mommy and daddy must have some SERIOUS drugs down there. :banghead: :banghead: :banghead: :banghead:
