CJ is not playing with a full deck.

Last night, I walked into the computer room to find Fleagor in my
chair. After I evicted him and sat down, he jumped up in my lap, then
lay down between the keyboard and the table edge - head to the left
and back to me - legs along the sides of the keyboard (he's a *large*
cat).

After a few minutes, CJ came in and jumped up on the table behind
Fleagor.  He sniffed Fleagor's butt, then settled down to clean
himself.

You must understand that while Fleagor is a rather peaceful cat, he
*is* the alpha male and rightfully expects a certain respect from the
other cats.  CJ picked fights with every one of the other cats shortly
after I got him - the ones he beat up hate him; the others mostly
dislike him.  He usually has sense enough to stay out of Fleagor's
way, but not lst night.

Fleagor took CJ's casual behavior inside *his* personal space as an
affront to his dignity.  He raised his head and looked at CJ for
several seconds.  Suddenly it dawned on CJ that he had done something
terribly stupid.  About a second later, Fleagor was still lying on the
table, but facing the other way with his back to the keyboard, a tuft
of white hair in his teeth, and a tuft of black hair in his claws.  CJ
was somewhere else.  Shortly after that, Fleagor wanted his belly
rubbed.  I later found CJ moving from a high shelf to a hiding place
in a corner of a closet.
