Two more Oregon cats died this month after eating raw cat food that was contaminated with the deadly bird flu virus, prompting Washington state officials to issue a recall.

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.

Pet owners cautioned after tests confirm Highly Pathogenic Avian Influenza (HPAI) in two cats living in different households.
