The death of an Oregon house cat from bird flu and a pet food recall are raising questions about how people can protect their pets.

Northwest Naturals issued a voluntary recall for a batch of pet food after a cat died of bird flu in Oregon, officials said. Testing done by the U.S. Department of Agriculture's National Veterinary Services Laboratories and the Oregon Veterinary Diagnostic Laboratory confirmed an indoor cat in Oregon's Washington County contracted bird flu and died after eating the pet food.
