H5N1 avian influenza continues to spread amid commercial and backyard poultry, and additional cases have been reported in domestic cats

California has also reported bird flu infections in cats fed raw milk or pet food. In one Los Angeles household, five cats got sick — and two died — after eating two kinds of raw pet food. Samples from one of the two brands, Monarch Raw Pet Food, tested positive for the virus, officials said.

While the risk of HPAI infecting people is low, it is not zero. The virus can infect people, especially those who come into contact with infected animals, materials, or surfaces.
