Grant County cat dies from ‘highly pathogenic’ bird flu, WSDA emphasizes risk

GRANT COUNTY, Wash. — A domestic cat in Grant County has tested positive for Highly Pathogenic Avian Influenza (HPAI), commonly known as bird flu, marking the first confirmed case in Washington linked to exposure to an infected wild bird.

The Washington State Department of Agriculture (WSDA) confirmed the presence of HPAI H5 in the cat, which has since died.

The cat, an outdoor pet, reportedly had contact with a deceased wild bird, believed to be the source of infection.

The Grant County Health District is collaborating with the pet owners, WSDA, and the Washington State Department of Health to provide guidance and preventive treatment to those who had contact with the cat.

No human infections have been associated with this case.

Dr. Amber Itle, WSDA State Veterinarian, emphasized the risk posed by migratory birds, stating, “Many migratory birds overwinter in fields, backyards and around water sources across Washington State. As birds concentrate, so does the avian influenza virus, increasing the risk of environmental contamination and spillover into domestic poultry, wild predatory species, and even our beloved outdoor domestic cats.”

The WSDA advises pet owners to take precautions to reduce the risk of exposure, such as keeping pets indoors or in covered areas and avoiding contact with wild birds. The department also recommends practicing good hygiene and avoiding feeding pets raw milk or uncooked meat.

Avian influenza is primarily found in birds but can infect other animals, including cats, foxes, skunks, and raccoons.

Symptoms in pets include decreased energy, respiratory issues, and neurological signs. Pet owners are urged to contact a veterinarian if they notice signs of illness.

Since the avian influenza outbreak began in 2022, 149 domestic cats in the United States have tested positive for bird flu, with four cases in Washington linked to raw pet food.
