Slick I cannot see how anyone could bash - very few people in the world would embark on such a long and painful journey.
It is good to hear Max is not in pain. Only you will be able to decide how HIS quality of life is and I know this counts for you much more than YOUR quality of life.
I can see that this journey comes to an end. Even little Filou is 6 lb and I cannot imagine how he would be at 4 lb- be glad that Max has such big fur around his poor little frame.
I am hugging you and give only very gentle kisses to Max.
