Two cats that belonged to Michigan dairy workers exposed to bird flu died after being infected with the virus last year.

But the study, whose publication was delayed by a pause in public communications by the agency, leaves key questions unanswered.

Cat owners should follow these tips, provided by the AVMA: Refrain from feeding cats any dairy products or colostrum that have not first been pasteurized or thoroughly cooked to kill the virus. Thoroughly cook meat before feeding, and avoid feeding raw meat-based treats or diets. Keep cats indoors to prevent exposure to birds and other wildlife.
