@McGentrix,
It's probably Unit 61398, trying to expand their zombie networks. You send "Kate" a hello, and the next thing you know, the FBI is knocking on your door trying to find out why you were attempting to hack the Pentagon.
Or it could be an insidious plot of Fu Manchu. You correspond with Kate and sooner or later you reveal something that can be used to blackmail you. Then you're forced to work for an opium ring, or possibly a white-slaver ring.
As long as we're chatting, allow me to say that there are altogether too many television commercials featuring Grumpy Cat. Or possibly not nearly enough. I haven't come to any definite opinions about that, but when I do you'll be the first to know.
