An update on H5N1 avian influenza

Cats drinking raw milk together outside

In March of 2024, a group of scientists from the Cornell Animal Health Diagnostic Center, in collaboration with other veterinary diagnostic labs, reported on the discovery of highly pathogenic H5N1 avian influenza (H5N1) infections in dairy cattle and cats on dairy farms in Kansas and Texas. Based upon the genetic similarity of the H5N1 strains found in affected cats and cows (and their milk) and epidemiological information collected in the affected farms, the presumption was that the affected cats most likely became infected by drinking raw milk from infected cows. Read more updates on how H5N1 has affected cats from the Cornell Feline Health Center.

Experts at the Cornell University College of Veterinary Medicine have provided a resource page for pet owners and the general public on highly pathogenic H5N1 avian influenza (H5N1).

Refer to this page for updates, recommendations and more information on this evolving H5N1 outbreak.

Recently, H5N1 influenza cases have been reported in cats that have consumed contaminated commercial raw food diets, unpasteurized milk, or had contact with wild birds and cattle.

Experts recommend that pet owners discontinue raw pet diets, and limit pet access to wild birds and raw milk.
