I assume (with my very limited scientific understanding) if it works with human blood it'd also work with animal blood, something you could likely pick up at your local Mom and Pop butcher without too much issue. Would save you cutting yourself open
Well yeah, but where's the fun in that? You can't put on some Linkin Park, put on your black clothes, paint your face white and then use cow blood. You have to cut yourself and then tell yourself that it's the light of your tortured soul... ;p
