Two domestic cats in Washington state have been infected with bird flu after eating raw pet food.

The state Department of Agriculture confirmed the virus in both animals based on test results received on Tuesday. Both of the cats had eaten Wild Coast Raw pet food, which was recalled earlier this month due to the potential contamination of the highly pathogenic avian influenza.

One of the cats was euthanized due to the severity of illness while the second is being treated by a veterinarian, according to the department. The pet cats belonged to people in King and Snohomish counties.

Five cat deaths in Oregon from bird flu have also been recorded, at least two involving the Wild Coast Raw pet food, which is produced in Olympia. For more information on recalls, pet owners can visit the Washington State Department of Agriculture’s website.

The most recent bird flu outbreak has spread through poultry and dairy cows and sickened some agricultural workers, though the strain is still considered low risk to the general public.

Cats are especially susceptible to the virus, which often spreads by migrating birds. Common symptoms include low energy and appetite, fever, hypothermia, pneumonia, and upper respiratory infection. The department encourages people with pets that ate the recalled cat food to bring the animals to a veterinarian immediately.

There is no documented case of a human becoming sick after exposure to an infected cat or contaminated food, but those who are around infected animals or who handle raw food are at a greater risk.

The department encourages caretakers to wear a mask and wash their hands when around a sick animal. Animals could also be isolated to prevent possible spread.
