I hate this guy.

Loud, stinky (and not the good kind), indiscriminately eats the weirdest stuff off the floor, sleeps alot, provides me with neither kibble nor Nip regardless of my pleading: I don't who this guy thinks he is, but a friend of mine he is not. In fact, if everyone has a nemesis, than I'd have to say that he's at the top of my list.
I find that getting above his mouth is the best way of staying alive; the window sill serves as excellent haven.
