t come into play in that theory because he realizes that he has more power, but your son is
the new comer . When your son is not in
his bed cover it with
aluminum foil, double sided tape, or saran wrap.. yes I know it will be a pain, but maybe if you can keep him out of the bed long enough for him to get used to your son's smell, he will not try to mark it. But in the end if nothing works I believe your are right, about finding him a new home, probably one without boys/males.
