H5N1, known as bird flu, has been found in San Mateo County this week, according to state and local health officials. San Mateo County officials said Thursday that bird flu was found in a stray cat in Half Moon Bay.

The growing bird flu outbreak in the Bay Area is a reason to contact your veterinarian if you suspect your pet could be ill. Health leaders on the Peninsula are warning pet owners to be on the lookout for symptoms after a stray cat came down with bird flu.
