oh well, might as well just feed it to ur pet rather than waste it.
Just put a hot iron to it and self-cauterize.
Oh **** (excuse my french), but that hurts and bleeds like crazy. You're going to have find a clean cloth and apply some pressure for awhile. I haven't done that in a while, but that's a pain that isn't easily erased from the memory banks, endorphins or not.
Wrap a section of cloth around it, be it from a towel or an old shirt or whatever to slow the bleeding, then get yourself to the hospital if you need stitches.
Be more careful, butterfingers.
