B-C government says a virus that has killed hundreds of feral rabbits on Vancouver Island has spread. Rabbit owners are being urged to take precautions after authorities say recent tests on dead feral rabbits in Nanaimo and Delta confirmed the presence of rabbit haemorrhagic disease. The government says dead rabbits found in the Comox Valley on Vancouver Island are being sent to the provincial lab for testing. Officials say the disease is exclusive to rabbits and does not affect cats, dogs, horses, other pets or humans.
