The "family room" (ha! read "junk room"), which also houses my computer, is Cindy's territory. She tends to hang out there in fairly equal proportions with our bedroom and the back yard. So she's often there, or will follow me there, and will come on my lap for a while to collect scritches. She even pushes the keyboard drawer out of her way. Mostly, though, she curls up a few feet away on her chair or the floor or in the window. Increasingly, I'm finding I have "bookends" -- Cindy to my left, and Fawn, a similar distance away curled up on the floor.
Suzy's computer hangout -- with or without a human -- is Rob's printer. She does herd him into the study when she wants his company though.
