A cat in Washington County, Oregon, has tested positive for Highly Pathogenic Avian Influenza (HPAI), specifically avian influenza type A H5N1. The outdoor cat, which had been exposed to wild waterfowl such as ducks and geese, was taken to a veterinarian after showing symptoms like fever, runny nose and eyes, lethargy, difficulty breathing, and loss of appetite. During the examination, the cat was diagnosed with pneumonia. The veterinarian reported the suspected case to the Oregon Department of Agriculture (ODA), prompting further testing.

The diagnosis was confirmed through collaboration between ODA, the Oregon Veterinary Diagnostic Laboratory at Oregon State University, and the U.S. Department of Agriculture's National Veterinary Services Laboratories. Preliminary tests indicate that the H5N1 virus contracted by the cat is not related to strains found in dairy cattle in other states. There are currently no confirmed cases of H5N1 in cattle in Oregon.

Cats—both domestic and wild species like tigers, mountain lions, and lynx—are particularly susceptible to H5N1 avian influenza. It is advised that these animals be protected from exposure to the virus. Dogs can also contract H5N1 but seem less susceptible than cats.

To protect pets from H5N1:

- Avoid feeding them undercooked or raw meat.

- Do not provide raw milk or colostrum.

- Keep pets away from wild birds and poultry.

- Prevent pets from eating birds or other wildlife.

- Wash hands after handling raw meat or interacting with animals outside your household.

- Change clothes and shoes after contact with animals before interacting with your own pets.

- Contact a veterinarian if a pet appears sick and report any potential exposure risks.

Veterinarians must report suspected animal influenza cases immediately to the Oregon Department of Agriculture at (503) 986-4711.
