>>36448662It depends on how you want to write /rrat/'s schizos but a "true" schizo requires some sort of deliberate conversion. Though I'm uncertain how common that knowledge should be in universe. And since the transformation is so dramatic I'd expect there to be some kind of ritual or myth associated with it so only some individuals would be suspected.
Also I tried like half a dozen combinations and they all don't work so I'll just post it in text form here.
