Oh my! I am sooo sorry for your loss, this post made me cry because I lost my Kiwi the same way a month ago today. I am so sorry you only got to spend such a short time with him, I feel like I was robbed of my little Kiwi to early as well. The only advice I can give is it does get better one day at a time. I still think of him and miss him everyday, but I can finally smile at his memories instead of cry. My thoughts and prayers are with you and your family.
RIP little Oliver
