Well if OP's brother is really young in a twisted way if kinda makes sense, I mean that's what happens when you cremate someone, it's just usually not done where one cooks their food or by someone other than a professional...
I totally see where you're coming from, 46, but it seems to me that if someone is old enough to know about cremation, then they're usually old enough to know not to put dead cats in an oven.
Serial killers often start by mutilating dead animals they find. Then they progress to killing small animals until it escalates from there. The more you know.
I'm very late but "randomcritic" likely meant that he'd believe the kid was a psychopath if he ATTEMPTED the cremation while the animal was still alive. Since it was dead, there's less of a fucked up twist and more of a sad misunderstanding.
Yeah, sorry, I was writing CAT and you are right, it autocorrected and by the time I went back to re-read the correction time had run out. Plus it wouldn't let me reply to my own comment before someone else did.
So, sorry for the typo and still sorry for the loss of a pet.
