I've got the giggles here too! Just this mental picture of Laura trying to sleep with kitties nipping at her hair even though she is burrowing under covers!! Attack of the hair seeking kitties!
I guess you could try spraying it with kitty NO! but then you would stink Wish I had a remedy! Surely it is a product they like, though - with Pokey doing it too I think your idea about rinse-rinsing it real good before you go to bed is a good one.
