The vet has the stuff to do the job. Let him bleed.
In the course of my life, I have been stepped on and thrown from horses, run over by cattle, bitten by dogs when trying to break up a fight. I have been spat upon by Llamas, slapped by a monkey and had snakes jump at me.
By far, a cat is the most dangerous when irritated.
LOL! I don't know about monkies and llamas, but cats hold a grudge - so even after they attack there is no guarantee they won't re-attack a week later...just because!
