Normally that would be viable, but unfortunately I was trying to play a traditional kumiho, and they diet subsist on the organs as far as I can see, the GM said I can eat livestock organs for the same effect, but it kinda takes away from the aspect, so I compromised for it being like an IV, filling the need but not being very satisfying. Apparently a collar that increases it's voltage in accordance to antagonistic acts isn't sufficient deterrent to him.

This was his reasoning. 

"1) An crappy electric collar is still not what I would call adequate measure to restrain an inhuman death row inmate"

Not sure what he thinks my characters pain threshold is, but slap a collar on Jack the ripper that shock the shit out of him every time he thinks about mauling a prostitute and I bet it'd stop pretty quick. Oh well
