Thank you all again. I am touched by your very kind words. The only news to report is that he is now unresponsive, after days of drifting in and out of consciousness. We continue to wait while this awful disease runs its course. I find that it helps to picture AJ stopping at Rainbow Bridge for a reunion with his beloved dog, who was his companion for many years. Then again, one of our cats might hiss at him--as much as he tried, he could not get on this cat's good side! Thank you again, friends.
