Oh my- these last pictures of Barney show how frail he is.
And no- no kitty pees easily in his bed.
I know I will have to take that decision some time- and I'm afraid it will be in this year to come so I wish you and Barney all the best for his long trip.
I know he feels your love- and being loved that much is the best thing that could ever have happened to him.
