Cats in two separate households died in May after developing severe illnesses that were confirmed as the Type A H5N1 bird virus found in U.S. dairy herds, investigators reported. Both were indoor-only cats that had no exposure to infected cattle or birds and didn’t consume raw milk.

A new report details the bird flu cases of two pet cats in Michigan whose owners work in the dairy industry. Earlier in the month, a data table from the report may have appeared on the CDC website before being taken down.

While the farm worker was never tested for influenza, this person did report a day of vomiting and diarrhea before the first cat got sick. One of the two adolescents in the home also reported a cough, sore throat, headache, and myalgia 6 days after the first cat got sick.
