A long time ago, my sister lived in a house that had a cat (or perhaps they just 'borrowed' it from the neighbours - I'm not sure). Anyway, they called that cat "C-for-cat" (where the "c" is pronounced like a child might say it). I transmogrified that sound into "Coofer" and so my name was created.
Today, some folks at work were delving the inestimable depths of the Internet and found an actual definition for "coofer".
From today, I'm no longer the mild-mannered Coofer Cat you once knew. No indeed. I'm now Coofer "Kicker of Pigeons" Cat. If you're a bird: beware! Grr!
