Just don't give up OP! My little girl was very difficult to litter box train but she got it eventually. In her case, I had to remove every soft thing in her enclosure because she was using her bedding and blankets as a toilet. The only soft surface she had access to was her hay filled litter box. It was tough for me, I felt like a jerk for taking away her comfy beds, but it worked. And now she can have all the soft blankets she wants and she does not pee on them.
