Yes, this is normal. It should subside with time, but personally, I did ensure the female bunny I chose had good litterbox habits. My rabbits will leave poop occasionally around the perimeter (I understand this to be territorial), or accidentally when they hop out of the litterbox, but for the most part, it stays inside the box. My bunnies aren’t able to be free range, but I would suggest slowly increasing a new bunny’s space instead of giving them complete freedom starightaway. When Thor was single and new to our home, backyard time always threw his litterbox habits off slightly, but cage time seemed to re-correct it. I don’t find Crysta marks more than Thor, but Thor is dominant so that may be the difference. Rabbits can learn undesirable behaviours from their partners. You never know whose gonna pass on what to the other. I had no idea Crysta was a chewer until after I’d adopted her, and now Thor has also started to destroy his cottage. Let me tell you, it was perfect before she came into his life. PERFECT. Then she demo’d a hole in the top level, and this week I’ve woken up to Thor picking up where Crysta left off. I’d heard of bunny “peer pressure” before, but I’m here to tell you it’s real, because Thor gets exercise so he has no excuse!
