Two cats in separate New York City households have tested positive for bird flu, the city health department says.

Officials in Pottawatomie County, Kansas, reported on March 6 that two cats had tested positive for bird flu. Owners concerned about the virus can keep their cats indoors and reassess their diets.

Cat owners are warned of more pet food recalls, as Savage Pet of California says some of its products could contain H5N1 (bird flu). The FDA and New York Department of Health share key information.
