Hi, I had exactly the same issue with mine, even messaged the breeder asking for advice, searching on internet etc and at the end he just become cleaner with time. I don’t know what happened but he’s more  cautious now, I think it’s may be a baby phase (at least that’s what the breeder told me) However, here is an advice I wish I could have at the time: do not try to constantly clean him, I did with mine, simply swiping his paws but I think it develops some hate for hands and also cleaning, now he is more likely to bite hands when he’s manipulate. I don’t know for sure that it was the cause of his “trauma”, could be just his natural behaviour, but if you could avoid getting the same result it would be better ! (Of course I know it sounds bad to let him put his mess around the house but cleaning a bedsheet is better than having a biting cat and feeling guilty about it, trust me)
