Sending all the good-positive-healing vibes I can muster, and said a prayer too! It's true, Gallbladder surgery is a pretty common deal these days esp with laprascopy, (doesn't mean it isn't scary for you). A year ago to the day my wife for some emergency surgery, so I kinda know how you feel. I am sorry for your cats prognosis, I like to believe that our pets go to good places too.
Take care,
Chris
