Yeah I see OP heavily revised this version of events, and worded it in a way that made it sound intentional. OP sucks and Milo’s death was absolutely avoidable from all sides involved. Yeah, he shouldn’t have left it out - not just because of her cat, but for any animals that would have gotten into it. It’s negligent. But so is letting your cat free roam, where it could find something like that 10 feet away at your neighbors - or 10 streets away. The cat could camp out behind an Autozone for all OP knows. And to purposefully fuck with someone’s mental health when 50% of the blame falls on yourself, also sucks.
