Ok, now I am off to CLEAN. I have a neighbor who is like this , there is just a little path to get from room to room. I don't go over there unless I just have too. But her and her husband don't see the mess or smell. They have 5 cats and 3 litter boxes one in the bathroom, one in their bedroom and one in the laundry room. All will get cleaned about every 2 weeks. They are the sweetest people you ever want to meet, but live like this and don't seem to care.
