I got a second rabbit at the start of the month, and she bonded with my first rabbit (male) quite quickly. They are both free-roam buns in a room, but Bramble has stopped pooping in the box. I have two litter boxes for them in different locations of the room, both with hay in them always. Bramble poops in the middle of the floor now, about half a foot from one of the boxes, but he still pees in them. Is he still marking his scent because of the new bun? How long might he do this for? Every time I see a poop on the floor I put it in the box, and every time I see him pooping outside of it I pick him up, put him in, and praise him. What else can I do? He used to have perfect litter box skills.
