At first it was the workbench. I could work around him or beat him with a carving mallet until he moved. But now he has taken over the printer:

Okay, the printer doesn't work but that isn't the point, is it?

Just look at him! Am I mistaken or is this behavior classic belligerence as described by Wooding and Meecher in 1904? If Mr. Toes' progression follows the standard disintegrative spiral, we can soon expect the cat to occupy normally open space with an appearance of tedium and/or disgust.
Oh NO! Holy crap! Do you see what I see?

Oh damn. No good can come of this.

I'm am not very comfortable with this situation. Has anyone got any experience with this sort of feline madness? I may not make it through the night.
