We had a bunny that dh made a trolley for so she could get around, while she was still eating we figured we needed to help her.
We decided to go on holidays and the day after we left, she died, I don't know if she was holding on for us or that she had, had enough. Her name was Big Bun.
If you look at the video, that bunny is starting to use her legs and getting her muscle back, that can only be a good thing.
