My ex-wife was an animal hoarder. She had tons of animals and her house was filthy and smelly. My boys, when they were about 9 or 10, would have to go over there for visitation. When they came, they would get into my car and my eyes would almost water from the overwhelming stench of cat urine and other foul odors. I tried to tell them one time about the smell and they got very upset thinking I was just trying to attack their mother. So, one time, when we got home I told them to go get a bath and to bring me their clothes. When one boy brought me his clothes, as soon as he walked away I put them into a plastic bag, tied it shut, put it into another plastic bag and then tied that one shut as well. The other boy brought me his clothes and I did the same thing. The next day, after they got home from school, I told the boys to come to the kitchen. I gave each boy the bag containing their clothes from the night before. I told the first to open it and to give a smell. He did so and snatched his head back in a hurry. I told the other boy to open his and give a smell.. He opted to pass. I told them those were the clothes they had on last night when they came back from their mom’s house. I explained that was what they smell like when they come back from their mom’s. I told them I wasn’t trying to say anything about their mother or trying to come between them…I wanted them to have whatever sort of relationship they were going to have with their mother not to be tainted by my views. But I pointed out that smelling like that was not good. And I pointed out the fact that once they were immersed in the smell for a while they could no longer really notice it as much. But other people could. I told them it could be embarrassing and they could be viewed as “the smelly kids”. I said I didn’t want that for them and I was telling them so they would be aware and could do something about it. After that, they still went gladly to their visitations with mom but as soon as they got home they stripped their clothes off, put them into the dirty clothes, and they ran for the shower, battling over who would get to shower first.
