And more government funding was required to conduct research into the best ways to control and eradicate them to protect wildlife.
Julia Nicholls, from the Australian Veterinary Association, said humane destruction of feral cats was required in national parks and agricultural areas.
‘Feral cats aren’t reliant on humans for survival and obtain food by hunting and scavenging,’ Dr Nicholls said.
‘They can also be very successful survivors in the harshest of conditions and are expert at avoiding capture.’
Dr Nicholls said though statistics were not readily available, the feral cat population was expanding and many eradication programs had failed to control their impact on native fauna.
She said there are still questions over the most humane and effective ways to control feral cats.
‘We need a lot more resources for research on the impact of feral cats on native fauna, and the best ways to control and eradicate them for the protection of our precious wildlife,’ she said.
