Welfare of Wild Rabbits in Myxomatosis Outbreaks

Myxomatosis causes prolonged suffering in wild rabbit populations and raises questions about disease management and wildlife welfare.

Key Facts

Myxomatosis was deliberately introduced to Australia in 1950 and Europe in the 1950s
It causes grotesque swelling of the head and genitals over 10-14 days before death
Wild rabbits show no pain behaviors outwardly but suffer significantly
The disease is spread by biting insects making containment impossible
Some European rabbit populations have developed partial genetic resistance

Welfare Considerations

Myxomatosis infected rabbits experience prolonged suffering including blindness from swollen eyes, inability to eat, extreme tissue inflammation, and secondary infections over 10-14 days. In the wild there is no humane intervention possible for the millions of affected individuals. The disease was intentionally released as a biological control agent without adequate consideration of animal welfare consequences. Euthanizing infected pet rabbits immediately is the welfare-appropriate response.

What You Can Do

Vaccinate domestic rabbits against myxomatosis where vaccines are available
Euthanize infected pet rabbits immediately rather than allowing natural death
Support research into myxomatosis vaccines and treatments
Advocate for wildlife welfare considerations in biological control programs
