Washington cats confirmed with HPAI as investigation into contaminated pet food continues

OLYMPIA – The Washington State Department of Agriculture (WSDA) is alerting pet owners that at least two domestic, indoor cats in King and Snohomish counties in Washington have become infected with Highly Pathogenic Avian Influenza (HPAI), with more cats being tested.

Pet owners reported feeding their cats potentially contaminated Wild Coast Raw pet food (previously identified in a prior public health alert). One of the cats was euthanized due to the severity of the illness. The second cat is being treated by a veterinarian.

The Washington Animal Disease Diagnostic Laboratory (WADDL) reported the presumptive positive results of both cats with HPAI on Monday morning, Feb. 24. WSDA received confirmatory results from the National Veterinary Services Laboratory (NVSL) Tuesday, Feb. 25.​

Preliminary test results show the cat, which got sick and died in mid-January 2025, was positive for bird flu. The indoor cat ate a raw pet food that is suspected to be the source of the infection.

This is the first case of bird flu in a cat in San Diego County. Several other unconnected cases have happened in cats throughout the state, and all are suspected to be the result of eating raw food or raw milk.​
