A. The best thing to do is find out what it the cause of the itchiness. It could be a wound from another animal and is infected, so he scratches. It could be from fleas causing him to scratch, which caused the wound. Once you know why it is there you can better treat it. In the mean time, don't allow him to scratch, this only makes it worse. You can try to keep the wound clean but its probably best to let the vet have a look at him.
