Two cats living in separate households in Multnomah County, Oregon, fell ill after consuming the raw pet food. After consultation with their veterinarians, owners of the animals agreed to euthanize the pets because of the severity of their illnesses, officials said.

This means four cats in Oregon have now been infected by avian influenza in the past two months, including two others in Washington County. The disease is more common among chickens and other poultry, but can spread to other animals through direct contact with infected birds or by consuming raw meat or milk.

The Oregon Department of Agriculture and the Washington State Department of Agriculture are alerting pet owners about the dangers of raw pet food.

Both cats that tested positive ate the same brand of pet food, Wild Coast Raw, before becoming ill, Oregon's agriculture department said. Testing confirmed the presence of bird flu in the cats and food samples,

Two Multnomah County cats were diagnosed with Highly Pathogenic Avian Influenza after eating raw pet food from Wild Coast Raw, prompting an advisory for customers to stop feeding the product.
