Sun-tzu in the Art of War said “Keep your friends close, and your enemies closer“. It seems Shadow has been doing some reading these days.
How are cats and yarn enemies you ask? Well I figure that to a cat yarn = knitting which = less petting time for the cat. That would explain why cats must attack yarn whenever possible, sleep on half-knitted items left lying out (to show them who’s boss), steal and hide knitting accessories, and to chew up knitting patterns left out on the coffee table.
