Well, like one cat in particular: Cassie.
Whenever I get up from the couch, even for 10 seconds, the cat immediately jumps onto where I was sitting, presumably because it's warm.
Interestingly enough, Jessica does the same thing. Probably for the same reason. Although she *says* "I'm saving it for you." Saving it from whom?
At least Jessica moves with a verbal command to do so. I have to practically sit on the cat to get her to move.
