It is very sad
Last year my family and I were driving to a shop when a wild rabbit walked across the road in a haphazard fashion. We parked and went back to the area it had crossed the road to and found it partially bald and the eyes were swollen and closed. It was myxi. I caught it in my coat and called the sspca who came out and pts the poor thing in their van. They were really fast, tactful and informative as I wanted advice on cleaning my clothes and the car to minimize spread to my bunnies (all vaccinated but still). I threw my jacket away as well just in case. The best thing is if these buns can be put out of their misery.
