Well, this is something my daughter found out she could do - if the kitty hisses at her, and she hisses back, it makes him hiss even more! So they were going back and forth at it for a while there - pretty funny! I've tried doing it but he won't do it for me, just her (he's always a little on edge around her anyway). She was petting and kissing his paws, and he just got sick and tired of it, I guess!
