So sorry for the sadness and suffering, and glad that you could set him free. It's such a hard choice to make, and such a loving one. I know one day I'll have to decide it for Ariel and Isaac, my two cats. They are so very present and give me nothing but love. What can we do but love them back, and set them free when to stay only means suffering? This will get easier, and his spirit will always be with you. L.
