So there's this carcass that's been decomposing by my house for a while and I wanted to ask if it was a bad idea or not to collect some of the bones for divination. And if I'm good to go, how should I go about it without you know... diseases, and cleansing/preparing them afterwards. Also which bones would I use for divination, my first instinct is ribs or forearms, (idk what it translates to animal wise)?
