WHY IS MY RABBIT POOING EVERYWHERE?

For the pee problem, he might be spraying. Put pee from his litterbox in the one in the other room. It might help him realize that that's where he's supposed to go. Our male bunny sprays, so we have to limit his access to the living room until he gets neutered. As for pooping, I honestly don't think they even know they're pooping. All four of my buns do the same thing. It's like it falls out as they run around. He might just not realize he's pooping, in my opinion.
