I love this! The science behind the kitten instinctively going motionless so mama can transport the fluff baby to safety... "scruffing" is the one trick to get Bobi the Bad to calm down when he goes after daughter's ankles (is it really only in play? He seems out to get the one person in the house who loves him and dotes on him the most - because she's the youngest/weakest?). You know your cats! Thanks for this post.
