Our cat Indigo is a secret sweetie. She likes to pretend that she is a grouch and doesn't care about anything, but she is always there to greet me when I come home, and she likes to crawl onto my chest when I am lying down, and knead with her paws while she nuzzles with her mouth. However - if you mess with her paws, her tail, or her mouth - or if you just mess with her in a teasing way, petting her belly or scritching her too much on her back - she can show you a quick response of "mock attack." What she does is lunge out with her head like a serpent, and *very* gently put her teeth on you, but not so as to hurt - and then immediately afterward, she licks, as if to say, "But I didn't really mean that." She is a great cat.
