Bird Flu Confirmed in Washington Cat, First Case Linked to Wild Bird Exposure

A domestic cat in Grant County, Washington, has tested positive for Highly Pathogenic Avian Influenza (HPAI), commonly known as bird flu. This represents the first confirmed case in the state 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 outdoor pet reportedly had contact with a deceased wild bird, believed to be the source of the infection.

This represents the first confirmed case in the state linked to exposure to an infected wild bird.

Public Health Response and Guidance

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 specific case.

Expert Warns of Increased Risk

Dr. Amber Itle, WSDA State Veterinarian, emphasized the risk posed by migratory birds. She stated that as migratory birds overwinter in Washington, the avian influenza virus concentration increases, raising the risk of environmental contamination and spillover into domestic poultry, wild predatory species, and outdoor domestic cats.

Precautions for Pet Owners

The WSDA advises pet owners to take precautions to reduce the risk of exposure, including:

  • Keeping pets indoors or in covered areas.
  • Avoiding contact with wild birds.
  • Practicing good hygiene.
  • Avoiding feeding pets raw milk or uncooked meat.

Understanding HPAI in Animals

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

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

National Context

Since the avian influenza outbreak began in 2022, 149 domestic cats in the United States have tested positive for bird flu. Four of these cases in Washington were previously linked to contaminated raw pet food.
