“Myxomatosis naturally occurs when the rabbit population increases,”Gloucester Rural Lands Protection Board senior ranger Laurie Mullen said.

Mosquitos are responsible for the transference of the virus and ideal weather conditions have helped mosquito breeding.

Myxomatosis is a pox virus that is characterised by skin tumours around the eyes.

The virus does not kill the rabbit, but blinds it, leaving it to starve or die in other inhumane circumstances.

There is no cure for the virus.

Local veterinarian Dr Paul Collins said the kindest thing for an animal suffering the disease is for it to be euthanased.

He also warned that anyone with pet rabbits should be vigilant.

“Keep an eye on the rabbits, especially for eye discharge and if it does occur see your vet,” Dr Collins said.

Dr Collins said it was also important to detect symptoms early to avoid it spreading to other rabbits.

The Department of Primary Industries released myxomatosis in the 1950s in a bid to control the feral rabbit population.
