It means she feels comfortable with you and trusts you! No matter how often I reprimand him, Gary still uses his hands to play with Shelly sometimes. They'll bat around at each other, and Shel never uses his nails. I think it's because he knows they're playing and he doesn't want to hurt Gary. He doesn't feel threatened, so no nails.
I'm tellin' ya, just hang in there! One of these days she'll bump ya and there'll be no turning back.
Shelly and Spooky have actually become lap cats. And Spooky used to run if you so much as held a hand out to her. In fact, no matter how much stuff is on Gary's lap, if she's in the mood, she doesn't even ask anymore. Instead of sitting next to him and looking up at him with pleading eyes, she'll just come trotting over and jump up there - no warning! Now we can't get rid of her!
So be careful what you wish for, LOL!
