A. if he has a scratch on his face it's either because a fought with another cat or because he scratched himself, I suspect the second option might be more likely. Usually cats scratch their face area because of itchiness or pain, which is usually due to either fleas, mites or ear infection. You could potentially get rid of all of those possibilities by using a good quality spot on like advocate. Those little scratches usually heal by themselves but if it looks infected or doesn't heal he might need antibiotic treatment at the vet as well.
