Hey guys, just thought I’d contribute by adding a couple tips– don’t forget that rabbits do not understand discipline, so don’t yell at her or bonk her on the bum, but putting her in the cage for a while could help her associate peeing outside her box with losing her freedom. Also know that rabbits will almost always go to the bathroom in a corner of their choosing, so look in her house and find which corner she’s been going in and move the litter box there. Another thing, she probably won’t be fully litter trained until she’s a little older, an adolescent, because baby bunnies pee a whole lot more than they do when they grow up. If you get her fixed when she is old enough she will be much easier to train and should stop going outside of her box. Lastly, never use litter for cats, because it is toxic for your baby bun. Don’t forget to study her closely and when she goes into her litter box, reward her with a few strokes on the forehead and a little bite of roughage– this will make her want to go in her litter box because she will associate it with reward and/or praise from her mama!
I hope this helps also, we all know how frustrating cleaning up pee can be! Good luck!

edit: forgot to add– You might want to buy another litter box for your room or wherever she roams, so at least she has the option in case she has an accident because she would rather not be locked up in her cage. On the other hand, it’s recommended you don’t let your bunny out of the cage for too long so that they have a much greater chance of learning the litter box a lot sooner. Buns are very clean creatures (you probably notice they clean themselves a whole lot) and they won’t want to be living in a real dirty environment… so they will eventually teach themselves over time. Be patient with her.
