The FDA has investigated bird flu outbreaks linked to raw pet food, which have sickened or killed over a dozen cats in several U.S. states. Reports include 13 domestic cats, one exotic cat, and animals at two big cat sanctuaries. Investigators are tracing the source of contamination, though results may take weeks. The FDA requires stricter safety measures for raw pet food, a growing market linked to increased disease risks for pets and humans due to the significant threat the virus poses to cats. Federal agencies have increased oversight of turkey slaughter, as a bird flu strain linked to raw pet food was traced to a turkey flock.
