Mistletoe, resident computer supervisor, has her very own spot on my
computer table.  I take two "bath sheets" (extra large terry towels), fold
them into sixths, then stack them next to the computer processor.  That's
Mistletoe's spot.

The table also has a swing-arm lamp with a 100W bulb (I like a LOT of light
when I'm doing work stuff).  The evenings have gotten a tad cooler of late
(<70F) so Mistletoe likes for me to swing the lamp arm directly over her
spot so she's got "soft underneath and warm on top".

The last couple of nights have been a bit warmer, so I've fired up the
computer without the lamp.  Last night, no problem.  Missy snuggled down
onto her spot with only the occasional "I'm here -- pet me" headbutt.

Tonight, I had to do some work so I slid the lamp over to illuminate the
papers I was using.  When I got done, I turned the lamp off.  Puttered
around the house for a few minutes then came back to the 'puter for RPCA.  I
had just downloaded the messages when "Mee-YOW, Mee-YOW"!

Missy jumped on the table, bapped the lamp back over her spot, then repeated
her demand.  Just for grins, I decided to ignore her.  15 seconds later, the
demands were repeated.  I didn't move.  Missy walked over, put one paw on
each shoulder and let fly with "MEE-YOW!  MEE-YOW!  MEE-YOW!, her face
nose-to-nose with mine.

The lamp was lit and she was appropriately stroked for her trouble.
