So by accident I found a good way to keep Jupiter from attacking my doorposts. I was planning to take out the paper waste but Jupiter started biting bars which indicates she wants to be let out. So I took her out for free running first. She loves to climb everything, and I mean
everything. So what I didn't think about but could have seen coming was that she would climb into the box with paper waste.
She absolutely loves it! She digs around and gnaws on the paper and climbs in and out of the box and I can really tell she enjoys it. It's really fun to watch as well, so I took a small video:
