Totally understand your fear, but that worry should be a long way off.
I've wondered if anyone has explained to him that his Red probably had DCM.
I hope you managed to read all of the article as it explained and made sense of why we feel the way we do when we lose a beloved pet. This guy certainly has a way with words. You can see how he makes his living writing.
It made sense of it, didn't make experiencing those feelings any easier lol sigh ...
I think the best part of the article is that it helps someone feel a lot less alone in their loss.
