Wick is not neutered, but is adequately litter-trained (can leave him out free-roam for half a day without an accident). For some un-neutered rabbits, it is possible, but for others, it may take a lot of time or not be perfect because of the territory-marking-instincts.
I suggest giving another (or two) litter box locations in the free-roam space. Wick has one litterbox in the bedroom (in his hutch) and two in the living room/kitchen area. As with litter training in a cage, you’ll want to try and catch your rabbit right before, during, or immediately after the act and plop him in a litterbox (if your rabbit isn’t stressed out by having you pick him up). Another option is when you see he’s about to pee on the sofa, start shooing him towards the box. Don’t chase, but try to coax his furry behind to the litterbox. Wick is quite familiar with the phrase “litter box”, and I always use the same tone of voice, so he understands what the words/inflection signify now. Wick has a lifted tail when he has a pee ready and squats down/perks his butt out when he’s about to pee. I would catch him right away (some times mid-pee) and carry him to the nearest litterbox.
The main idea is now that he’s free-roam, he needs to try to grasp the concept of “I need to move somewhere when I need to pee” and “I can’t pee here”. With Wick, action via re-location before/during piss & poop worked well. Excessive praise when he succeeded works as a great reinforcer too. Also, I added pictures of Wick’s litterboxes to show a nice design for litterboxes in a free-roam space which minimizes peeing out of the litter box while in it, as well as keeping hay contained so it doesn’t track in your space too much.
