Myxomatosis is a viral disease introduced to control wild rabbit populations that causes prolonged suffering and remains a significant welfare concern.
Few diseases cause as much prolonged suffering as myxomatosis. Affected rabbits become blind, unable to feed, and remain alive for one to two weeks in a state of severe distress. Wildlife rehabilitators frequently face decisions about humane euthanasia of infected animals. The disease raises profound questions about the ethics of using biological agents to control wildlife populations, particularly when the suffering imposed is so severe and extended.
