(I suggest either taking a shower or changing your clothes. As for your cat, I would go to walgreens or safeway and picking up some hydrogen peroxide. Or, if you don't want to do that, hold your cat down by the scruff--then he/she relaxes a bit, but don't hold it too hard, it might hurt him/her--and pour the salt water over the wound slowly so that your cat doesn't flip that he is in a bath tub of water.
Or, the best thing to do, is call a vet.)
