Cats can be infected with the high pathogenic avian Influenza H5N1 if they eat raw H5N1 infected birds. The virus can spread from cat to cat probably through contact with feces, urine and respiratory secretions. Clinical signs are non-specific and typical of severe respiratory infections. They include fever, lethargy, labored breathing and death.
Avian influenza infection in cats has only been seen in areas of the world where H5N1 is prevalent.
Cats have not been shown to be susceptible to low pathogenic or other strains of pathogenic avian influenza virus.
