Cats highly susceptible to H5Na avian influenza

KEEPING domestic cats inside has never been more important, experts say, as the number of confirmed H5N1 avian influenza cases on Australian soil hits 20 and affects four states.

While all detections of the highly infectious bird flu have so far been among migratory seabirds, the variant is known to affect more than 100 species of mammals, including felines.

Global research has indicated the mortality rate among infected domestic cats is between 50 and 90 per cent.

Animal Care Australia has advised pet owners, particularly those with cats and backyard birds, to take precautions now because cats can become ill following contact with infected birds or contaminated environments.

“Free-roaming cats are at a much higher risk of exposure to H5 bird flu,” the organisation said.

“Keeping your cat indoors or safely contained significantly reduces exposure and injury risks.

“Cats need secure housing and care now more than ever.”

The disease spreads easily through direct contact, droppings, respiratory secretions, or contaminated surfaces, feed, or water.

Cats are more likely to catch H5N1 as they are more likely to seek out or encounter sick or dead wild birds. Dogs, to a lesser extent, are also susceptible to the zoonotic disease, but the mortality rate is much lower.

Symptoms to watch for in cats include fever, lethargy, loss of appetite, severe eye or nasal discharge and difficulty breathing. Neurological signs can include tremors, seizures, or blindness.

The infection can progress quickly, so if people spot signs they should contact a vet immediately.

Official advice is available from the Department of Agriculture, Fisheries and Forestry (DAFF) or Wildlife Health Australia websites, and any information can be reported to the 24-hour Emergency Animal Disease Hotline on 1800 675 888.
