Environmental groups call for pet cat confinement laws to slow bird flu
Grassroots environment groups are calling on the South Australian government to urgently introduce state-wide laws requiring all pet cats to be confined to their ownersā properties 24/7.
In a joint statement, 21 volunteer environmental groups in the Adelaide Hills (listed below) say pet cats can contract H5N1 avian influenza from catching, killing or eating infected creatures.
āCats are highly efficient and indiscriminate apex predators ā because they hunt so many different species, they are a significant vector in spreading the virus from wild birds into new bird and mammal populationsā a spokesperson for the group says.
āAustralian ecosystems are already under immense pressure from feral and roaming pet cats, which kill millions of native birds, reptiles, and marsupials every day. As bird flu takes hold in local wildlife populations, outdoor pet cats hunting or scavenging infected animals will accelerate the spread of the virus.ā
āIntroducing restrictions on domestic cats is a critical conservation strategy to help shield Australia's unique and vulnerable native wildlife from the catastrophic threat of avian influenza. A roaming cat that catches an infected bird can easily transport the virus across suburban boundaries into fragmented bushland reserves, national parks, and coastal shorebird habitats.ā
āTo help slow the spread of bird flu, we call on the South Australian Government to introduce State-wide laws requiring all pet cats to be confined to their ownersā properties at all times,ā the spokesperson says.
āAs well as spreading the virus, cats are themselves susceptible to the disease. It can kill them, and it can present a risk to their households. A cat returning home after an outdoor excursion could shed the virus through saliva, nasal secretions, and faeces. Keeping cats inside ensures that the home environment remains a secure sanctuary.ā
Further, the groups encourage owners to adopt an indoor-only lifestyle for their cats, to eliminate the risk of their pets becoming infected through wildlife encounters, reducing harm to wildlife, households and pets.
