@AllsfairinloveandbugsUpdate: we now have a peg-leg princess. I kept her up a few days after the accident, she got around fine after, and yesterday, two months to the day it happened, I went out to find her with a peg leg. Little bloody, so I put her up in a crate with a friend, and am looking into a silicone leg cover and prosthetic foot.
Have any insight for OP?
