I'm usually a fan of depressing stories, but We3 was too much for me, and I suspect might be too much for any animal lover. It's heartbreaking, and that's the only way I can classify it. Not good, not bad, just heartbreaking. If I could, I would probably go back and un-read it, because it's a sad that I can't scrub from my mind, even though I'd dearly like to. 
 You've been warned.
