I have a roll-around radiator style heater I keep next to Napkin's kitty condo. She is quite contented with this arrangement!
And I've found with her if you want her to lay on something the following steps never fail:
Put a price tag from an expensive shop on the item.
Hold the tag up to her face, and say "NAPKIN! This is a VERY EXPENSIVE ITEM! Whatever you do, DO NOT SLEEP ON THIS!
Of course, with her quest for the finer things in life she will immediately lay on the item.
