What makes Numnum so mean?

My brothers have cats. My sister has cats. I didn't until one night when I discovered him hanging out alone since his mate had disappeared in the dryer. I luckily had a digital camera available to catch his wooly visage before he left, seldom to be seen again. How was he mean? He made me eat dust bunnies, taught me bad words, and smelled awful...like a cross between well-aged cheese and dank fen scum. I am sure he is still somewhere in the neighborhood, though I never see him, exactly.
