I too find it so significant that B. had fought hard and long for you, and when he could fight no more, he could do one last thing and that was to see and to say good-bye to his mommy. When he was once more in your arms, he felt safe and ready to make his final journey. This is so sad yet such a testament to the bond you and he had. I have been privileged to know Mr. B. through you. I am so so sorry for your loss. Please look into the eyes of your other little fur babes to know there are many reasons to fight back from the sadness. Look to them. They will show you the way.
