My Iris seems to think I'm in the mood to play when I sit down at my sewing table. She's so cute I can't get angry. I did come across something that works but you have to do it periodically. I guess they forget? Or maybe they think you really aren't serious! Anyway, sneak up on them when they are where they aren't supposed to be & make a sudden loud noise. I use a pot lid & a metal spoon. Iris hates it but she's stays off the table temporarily.
