I am sorry to hear about your problem with Lupin (love the name!). If he had previously been using a litterbox well and out of the blue started urinating all over then I would be concerned we could have a medical issue like an infection or kidney problems and would recommend a visit to the vet. If this is an ongoing issue it could be territorial marking especially if he is an unneutered rabbit, or a behavioral reaction to too few litterboxes, dirty boxes, or changes in the environment. I would recommend reading this article: https://articles.extension.org/pages/33013/rabbit-behavioral-problems:-inappropriate-urination which provides some insight into possible causes and how to remedy the situation! Best of luck to you and your bunny!
