Gotta love cats, they have such personality. I've had so many kitties, that I think I've seen almost every trick in the book at least once. There were a couple we had when I still lived back home that did this. The momma cat, Brandy, loved to get up and across anything you were doing. Her favorite spot, for some odd reason was on the accordion case,and lying across mom's music. Her daughter, Whiskey, has a great indicator of cold temps. Just before it would start getting cold, she'd take up her customary spot right across the floorboard vents in the livingroom because they were the warmest spot in the whole house during the winter. Neither her mom, nor her big brother Boo (a 15 pound yellow tiger), could get her to move from that spot and if they were there and she wanted the spot? She'd carry on until they moved. Heh. The runt of the litter, and SHE ruled the roost!
