Mutated H5N1 Bird Flu Found in Cats: Scientists have identified a genetic mutation in two infected cats that is linked to increased infectiousness and disease severity. Mutation Similar to One Found in Cows: The mutation, PB2 E627K, is similar to one found in San Bernardino dairy cows, though the cats were infected with a different strain.

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.
