SYDNEY, Feb. 7 (Xinhua) -- A deadly cat virus has re-emerged in Sydney after not being seen for 40 years.
An animal holding facility in the city's west was forced to shut its doors to cats after an outbreak of the panleukopenia virus, often called feline enteritis.
"Please do not bring cats to our Animal Holding Facility until we are sure the epidemic has passed, and because other facilities across Sydney are affected, cat owners need to check the status of any facility where cats are held," Blacktown Mayor Stephen Bail said in a statement on Tuesday.
It's believed that the outbreak could be due to owners not getting their cats vaccinated, thinking it unnecessary and believing disease to be extinct in Australia.
A similar disease can also effect dogs, authorities are urging people to vaccinate their animals.
At this time, three other animal shelters across the state have informed the public not to bring cats.
