I just got 2 rescue cats two days ago. They are brother and sister and inseparable. One of them is pooping in the litter box, but he is not covering it up. He is then getting it on his feet and tracking it around the house. The litter box has plenty of litter and I am cleaning it at least twice a day. Any suggestions?

Dominant cats will sometimes leave their poop uncovered to let other cats know that they are around and claiming the territory. Don't know what you can do to stop it.
