Randi, please try not to worry. My Storm just had his teeth cleaned and 2 of his upper tiny teeth were loose so they were removed. He's almost 12 1/2 years old and he did fine. There are different kinds of anesthesia and it said that Storm did well with induction with propofol,maintenance with isoflurane, and buprenex injection for pain control in the hospital. I'm sure that Fister will do fine and I'll keep him in my thoughts and prayers.
