I have this probelem with my Skye. She is a well socialized kitty. Even to total strangers. Yet whenever my roommate has his children (3 & 2) over she gets really edgy. She hisses, bites and tries to scratch them even if they are simply walking by. Is there some reason she could be doing this to only them. I try to remind them to be extra nice to her and not to startle her but she still hates them.
