If you can't block her from going onto your bed. Use something to cover your bed, such as a plastic cover. I used a plactice shower curtain. My girl used to poop on my bed too. But after spaying, she stopped doing so. Cleaning bunny's scent with vinegar is the best choice for me. No matter how good you think you can get rid of her smell, she still can smell it. That little nose can smell things wa better than us. Is your girl spayed ? She might do that to claim that the bed is hers, or to let you know that you're hers.
