Wick is free-roam 24/7 in my entire living space, with exception of the bathroom which is typically kept close. It’s a blessing and a curse. Blessing because he’s very much a family member and integral part of everyone’s daily routine, but also a curse, like this morning he jumped on his other parent’s face while he was still sleeping in bed. Much to his parent’s dislike, as you can imagine.
Whether litter trained or fixed, I find most rabbits will mark for a bit whenever they enter new territory. When I move from my current place and move all the furniture out, there will definitely be splotches of old pee and poop I’ll need to clean. Wick no longer marks outside his litterbox (with some health-related exceptions and attitude-related exceptions), so while initially it was crazy to maintain, now it’s much better.
I do keep in mind that Wick is not a destructive rabbit, so rabbit-proofing is not a big concern, which is why I am very comfortable having him free-roam.
