I just recently bought two ferrets and what's odd is that my little girl is potty trained but my boy isn't. He poops EVERYWHERE and I have to clean the cage constantly. I took out all the levels because the pet store I bought them from recommended that and it still doesn't work. I will add a picture of how their cage is set up. Any tips will be really appreciated. In the picture I just finished cleaning it. I use vinegar and water mixture.
