Urinating & Deficating in Bedroom

Rapahel did this. He did it on purpose and made the other kids watch and he did it on the walls, in the closets, in the dryer (ugh) and everywhere. I thought it was a new dog we had gotten and got rid of the dog. Since the kids were scared of him, they were afraid to say he did it. My kids also claim he ate it, but that's so farfetched I don't want to believe it. I was told this behavior is rage and often seen in kids who have been sexually abused. Although Raphael has no memory of having been sexual abused, it is everyone's feeling that he had been....and had blocked it out. It took us months to get rid of the odor and I agree with Lucy Joy that it is deliberate and done out of fury. I have no idea how to stop it, but, if I had known he was doing it, I would have given him a wash rag for sure!
