During the canine influenza incursion, which HxN subtype was associated with respiratory disease in cats?

Explanation:
H3N2 respiratory disease in cats demonstrates how influenza A subtypes can cross species barriers and affect different hosts during a canine influenza outbreak. The H3N2 canine influenza virus, originally avian in origin, spread to dogs and also infected cats, causing feline respiratory illness. Other subtypes in this context—such as H5N1, H3N8, or H1N1—do not have the same well-documented association with cats during the canine influenza incursion. Therefore, the subtype linked to cats’ respiratory disease in this scenario is H3N2.
