What Animals Can Eat

[Xyntak]

I know this is probably a pretty simple task, but I am completely new to changing anything in Rimworld. I would like to be able to make rates (and maybe other creatures) consume all phases of corpses. This way, I could put a whole bunch of fresh, rotten, and desiccated corpses in a room with a bunch of rats and by doing that I could feed the rats and get rid of the corpses. Any idea how I would do this?

Thank you for your help,
