This sounds like your cat had a cat bite abscess, If you can make sure all the green goop (pus) is evacuated. If you have a mild wound disinfectant at home you can flush the cavity. Make sure all the liquid is out. It should heal by itself, if not your kitty needs to be seen by a vet and will likely need prescription antibiotics.
