My new four boys go potty in just about any corner of their cage, including the top shelf next to their food bowl. I've put a litter box in one corner, and have tried moving their mess into it every hour to try and get them to go in it instead, but with no luck. It would be fine if they only went in their cage, but when I try to let them out for playtime they will go anywhere and everywhere and I don't know what to do about it. I have a specific blanket I use for when I hold them, clean their tails, etc. because they always poop and pee on me. Is there any way I can fix this behavior? My two girls have never done this unless I keep them out of their cage for too long, so I don't know how to deal with it.
