Jenna,

I am so sorry for your loss. Despite his handicaps, Igor had a good life with you and probably wouldn't have lived as long as he did with someone less knowledgeable. The other thing that might be on your heart is the fact that you were on vacation and wasn't his primary caregiver. Don't feel any quilt about that, I've been there and done that and it doesn't serve any purpose. Just remember that he had a good life.
