Update:
I sparyed him with the dish sprayer in the kitchen, he was PISSED! but I knew this would make him lick himself dry and it got rid of the blood on him. but........
I was so concerned with him, I didn't notice the blood on the carpet, I just told my gf that I had an ingrown toenail that bled when I cut it out. So I still got shit about ruining the carpet.
they are both lucky I don't own a woodchipper!!

P.S. Thanks for all the ideas, especially liked the toilet one!
