Since you mentioned that you have both bedding and litter, it sounds like you have bedding all over the bottom of his cage. That confuses a rabbit, and it will make them go all over the cage. You need to have a large enough cage or an x-pen to hold a adequately sized litter box, and only have litter in the box. Don’t have any litter or bedding in other parts of the cage. If he isn’t a chewer, you can have towels or fleece blankets for him to sit or lie on in the cage, or grass mats.
