I'm pretty sure the cat isn't asking for a hug. You have to realize that most of these emotions you think the cat is doing is just a coincidence because a cat does not possess specific human emotions. If you think a cat is smiling, it really isn't. It's just the way the cat looks because of its mouth. If you think a cat needs a hug, it doesn't. It's just stretching.
I'm sorry, what was that? You friggin NERD?

This cat is quite clearly standing up like a human, politely requesting attention like a human, and being petted. Hell I'd even bet afterwards it says "Thanks madam, that was purrfect" and gives her a $20 tip.
Don't underestimate cats bucko. mawty taught me that a long time ago.
